Sand and mud deform u nder foot\, while even rocks and ice are “squishy” on geologic timescale s. This skin of particulate and living material is fragile\; excited by a broad spectrum of perturbations\, Earth's surface flickers across meta stable states. Understanding this soft earth geophysics is existential\, to manage the risk of increasingly dangerous natural hazards such as la ndslides and earthquakes and to learn to build with sustainable geomater ials. This emerging field centers on identifying and advancing common fr ontiers in geophysics and soft matter physics. Recent studies have revea led how Earth’s surface creates and maintains novel out-of-equilibrium m aterials and transport phenomena. The memory of earthquakes and floods is encoded in the microstructure of sediments\, friction and cohesion co nspire to create the wide range of yielding behaviors and feedbacks bet ween organisms and their environment shape flow.This program seeks to co alesce a community of scientists from soft matter physics and geoscience \, to collectively define a set of outstanding questions\, and to develo p novel approaches to answering them. Scientific themes include metastab ility and state transitions (e.g.\, creeping and yielding)\, localizatio n of strain/failure and the emergence of collective motions\, active mat ter of the living Earth\, creation/erasure of material memory\, and extr acting physics from geophysical observables. This program will also incl ude pedagogical lectures and skills-sharing activities\, to foster commu nication and inclusion among scientists from the diverse backgrounds nee ded to advance this new field.

At the same time\, possible te nsions between different probes provide hints for where it may break. Su rveys ranging from radio\, microwave\, and optical to X-ray are in progr ess or soon will be\, promising to deepen our understanding. These surve ys aim at answering cosmological questions regarding inflation\, the nat ure of dark matter\, dark energy and gravity\, the value of the neutrino masses and the number of light relics. They also promise to shed light on galaxy evolution and the state of baryonic matter in and among galaxi es and clusters of galaxies. While different surveys leverage different observables and methods\, their success often relies on information that is provided from other surveys. The primary goal of this program is to bring together scientists with expertise across such diverse surveys\; t ogether we aim to develop innovative ways to combine these data sets to enhance our understanding of astrophysics and cosmology. We anticipate t hat participants will develop and test these new approaches at the progr am as data from a variety of surveys becomes available.

Quark-gluon matter encompasses t he hot strongly-coupled liquid known as Quark-Gluon Plasma (QGP) that fi lled the early universe and is produced in heavy-ion collisions. To the surprise of the broader particle physics community\, quark-gluon matter signatures have been measured in high-multiplicity proton-proton and pro ton-lead collisions\, opening up experimental inroads to study not only the properties of quark-gluon matter but also the dynamical non-equilibr ium processes that lead to its formation. This program will critically a ssess the theoretical description of the properties and dynamics of quar k-gluon matter\, and identify the future challenges of the field in the next decade. In particular\, we aim to bring new theoretical insights th at will deepen our understanding of existing and upcoming experimental m easurements. Key to this goal will be a vibrant environment that will br ing together heavy-ion experts with researchers of three neighboring fie lds: high-energy particle physics\, nuclear structure and formal theory. The program will push the boundaries of the precision frontier with emp hasis on the role of out-of-equilibrium QCD\, nuclear structure\, global analyses\, and high-energy probes and the quantum frontier\, where form al theoretical developments related to conformal field theory\, holograp hy\, and confinement meet our understanding of quark-gluon matter.

Fenton ATTENDEE:Daisuke Sato ATTENDEE:and Yohannes Shiferaw DESCRIPTION:Cardiac arrhythmia is a leading cause of death\, but its unde rlying mechanisms remain poorly understood. This failure is largely due to the complexity of the heart which is a multi-scale system that depen ds on nonlinear interactions across a vast range of spatial and temporal scales. Unraveling the underlying mechanisms for arrhythmias requires an integrated approach that will require state of the art experimental methods along with theoretical and computational insights. This program will bring together experimentalists\, clinicians\, and researchers from physics\, mathematics\, and engineering to explore arrhythmias from the molecular to the whole organ scale. The first week of the program will explore recent progress on the molecular basis of cardiac arrhythmias\, specifically examining how genetic disruptions can initiate these condi tions. In week two\, the program will focus on the latest progress on c ellular-level phenomena such as disturbances in calcium signaling and th e formation of dangerous electrical excitations. The third week will e xplore tissue-scale phenomena such as ectopic excitations and reentry. The final week will be dedicated to translating these scientific insight s into clinical applications. Throughout the program\, there will be a s trong emphasis on fostering collaboration between experimentalists and t heorists\, with the goal of developing innovative tools for diagnosing\, predicting\, and treating arrhythmias.

Each hear tbeat arises from the collective behavior of billions of cells communica ting through waves of electrical excitation\, nonlinear signals that can synchronize into steady rhythms producing the regular contractions of t he heart.\n During arrhythmias\, these electrical waves can become disor ganized\, creating complex and irregular patterns such as spiral waves t hat drive uncoordinated contractions\, disrupt normal blood flow\, and c an become life-threatening. In both normal and arrhythmic conditions\, t he organization of these waves exhibits emergent behavior that arises no t only across multiple scales but also across dimensions\, from the dyna mics of a single cell (0D) to one-dimensional strands of tissue\, two-di mensional wave fronts\, and the full three-dimensional geometry of the w hole organ. At each level\, emergent patterns and instabilities arise fr om the interplay between the dynamics of ion channels governing current flow across individual cell membranes and the collective cells coupling within the complex architecture of cardiac tissue\, which together shape the propagation of electrical waves and resulting mechanical contractio ns.\n In this Teachers’ Conference\, we explore how physics\, mathematic s\, combined using computer simulations and experiments reveal the princ iples that govern the heart’s rhythm\, and how this understanding is lea ding to new ways to control and prevent cardiac disorders. Topics will i nclude excitable-media dynamics\, wave propagation and spiral waves\, de fibrillation\, and emerging therapeutic technologies such as pulsed-fiel d ablation. These concepts will be discussed through the lens of fundame ntal physical ideas such as diffusion\, nonlinearity\, chaos\, and patte rn formation in living systems\, highlighting how they can be incorporat ed into the classroom to engage students at the interface of physics\, b iology\, and medicine.\n The conference includes talk by speakers who ar e leaders in experimental\, theoretical\, and computational biophysics\, participating in the KITP program “Multi-Scale Physics of Normal and Di seased Heart: From Ion Channels to Whole Organ.” In addition to talks\, the conference will feature interactive presentations (experimental and computational) where participants engage directly with demonstrations th at illustrate key physical and biological principles\, activities they c an later adapt for use in their own classrooms to teach biophysics.\n In order to accommodate participants' holiday travel plans\, the conferenc e will run from 9 AM - 3 PM.\n Particle Physics: At the Heart of Matter Coordinators: Kenneth Cecire and Shane Wood \n On Friday\, April 3\, KI TP will also host the workshop "Particle Physics: At the Heart of Matter \," presented byQuarkNet. The full-day workshop (9 AM - 4:30 PM) will fo cus on activities from QuarkNet's Data Activities portfolio and explore particle physics leading to connections with BioPhysics\, the topic of S aturday's conference.\n In order to participate in the Friday workshop\, you must also register for the Saturday teachers' conference. If the wo rkshop is over-subscribed\, priority for that activity will be given to physics teachers and to applicants with less QuarkNet experience.\n A fu ll description of the workshop content will be published in January.

Typical electromagne tic excitations of nuclei correspond to x-ray and γ-ray energies (10⁴–10 ⁶eV). The exceptionally low isomeric excitation energy of 8.4 eV in Th-2 29 results from an accidental cancellation between two very large energy scales: the Coulomb and the strong-force energy. The large values of th ese energies and their near cancellation make the Th-229 nucleus an exce llent testing ground to look for time variation in the fine structure co nstant (which would affect the Coulomb energy) or to search for interact ions with dark matter (which might affect the strong-force energy).Recen t breakthrough experiments have located the aforementioned 8.4 eV narrow resonance of the nucleusand directly excited it with laser light. Indee d\, a recent experiment based on a precision optical comb has directly c onnected the frequency of UV laser light near 8.4 eV to an optical atomi c clock and has determined the Th-229 excitation frequency with 12 signi ficant digits. This nuclear isomeric transition has numerous advantages for use in precision timekeeping and quantum sensing\, building on the p ossibility of employing a huge number of nuclei embedded in a solid-stat e host. However\, this platform has an array of challenges such as inhom ogeneous line broadening and systematic frequency shifts. Overcoming the se challenges will require coordinated and synergistic efforts among dis parate fields of nuclear\, atomic/optical and condensed matter physics. Motivated by these goals\, we will explore the following topics:\nImplic ations for fundamental physicsDefects and ionic configurations–theory an d experimentLinewidth broadening mechanismsTrapped ion vs. solid-state p latformsFast readout of nuclear statesSolid state hosts with gaps <\; 8.4 eVOptical resonators at 8.4 eVNew highly coherent\, higher power VUV laser URL:https://www.kitp.ucsb.edu/activities/thclocks-m26 SUMMARY:Thorium-229 Nuclear Clocks ORGANIZER:Steven Girvin, Eric Hudson, Leo Radzihovsky, Marianna Safronova , Thorsten Schumm, and Jun Ye LOCATION:KITP BEGIN:VALARM TRIGGER:+P3628800D DESCRIPTION:application/registration deadline!

Despite this impressive scale\, these qu antum devices have not yet achieved tasks surpassing classical capabilit ies due to the substantial resource overhead associated with digital gat e-based fault-tolerant error correction. Consequently\, there is growing momentum to explore hybrid quantum computing approaches that merge anal og and digital techniques.This conference will bring together researcher s from quantum physics\, computer science\, engineering\, and mathematic s to tackle a crucial challenge: demonstrating quantum advantage on pre- fault-tolerant quantum hardware without complete reliance on traditional error correction methods. Participants will investigate innovative quan tum algorithms\, advanced quantum error mitigation strategies\, and spec ialized pulse-level control methods tailored for large-scale quantum sys tems. Ideally\, the conference wouldserve to articulate the nature and scope of quantum advantage that can be achieved in the near term\, drivi ng immediate and impactful scientific and technological breakthroughs.

Notably\, developments in large deviation th eory\, stochastic processes\, high-dimensional dynamics\, and optimizati on promise to push these advancements even further when integrated with insights tailored to the specific questions within each field.The object ive of this program is to apply these powerful concepts to evolutionary dynamics\, population dynamics\, and active matter\, and to explore the cross-fertilization between these areas. Some of the questions we aim to discuss during the program include: How can evolutionary dynamics benef it from paradigms developed within active matter to incorporate physical space and environmental heterogeneity? Conversely\, how can active matt er leverage the language of networks and high-dimensional dynamics\, wel l-developed in evolutionary dynamics\, to capture the hierarchical organ ization that leads to emergent phenomena of interest? Furthermore\, how might recent advances in large deviation theory and optimization in hig h-dimensional spaces be integrated into this interdisciplinary study?By addressing these questions\, the program aims to foster a deeper underst anding and uncover new insights into the complex behaviors and dynamics across these fields.

Yet\, knowing which genomes are present in a given environment is not enough to understand how communities assemble and function.Genes are st rongly coupled with organisms and the community that harbors them. Envir onmental conditions affect gene expression and the realized community me tabolisms\, which in turn modify the environment. This feedback shapes i nterspecies interactions and community states. Physiology is key to deco ding the gene-organism-environment triad\, but our knowledge is limited to a few species in controlled laboratory conditions. However\, getting a quantitative understanding of the physiology of all the microbial spec ies present in a community is an impossible task. As such\, to get a qua ntitative understanding of microbial assembly and function across enviro nments\, we need a framework to identify relevant coarse-grained physiol ogical traits from (meta)genomes. To this end\, a cross-disciplinary app roach is required.The program will assemble a diverse team of experts sp anning the fields of environmental microbiology\, microbial physiology\, ecology\, and physics to advance three core research areas: 1) understa nding to which degree physiological strategies can be inferred from geno mes\, 2) define which traits are relevant for microbial community assemb ly and under which environmental conditions\, and 3) develop a framework to integrate physiological traits into theories of microbial community assembly.

But l earning is a potentially broader metaphor\, applicable to physical and b iological phenomena that may not involve neurons at all. This program pu ts forward the nontrivial hypothesis that learning can be a useful frame work to organize questions about a broad range of systems that acquire f unctional behaviors by accumulating incremental changes due to environme ntal stimuli over their history. These examples range from reconfigurati on of vasculature networks in slime mold and changed behaviors in ciliat es and other single celled organisms in response to structured environme ntal stimuli\, to the generation of broadly neutralizing antibodies in t he adaptive immune system. Minimal systems that have provided insight in to possible mechanisms for such `physical learning’ include mechanical a nd molecular systems that learn to deploy specific elastic\, phase separ ation or self-assembly behaviors. In these and other examples\, systems adapt locally but confer global function.Despite the recent proliferatio n of examples\, the unifying key principles of such adaptive processes h ave not yet been distilled. In parallel\, the theory of learning is unde rgoing an accelerated development propelled by machine learning. This pr ogram will bring together physicists\, biologists and neuroscientists to refine key questions–what kinds\, or classes\, of natural local process es in different physical and biological systems allow them to learn? Wha t kinds of statistical structure in environmental stimuli can be learned by a given physical system? What physical properties and architectures allow for learning more complex internal models of complex environments (expressivity)?

What determines the emergence of organized patterns\, the timing of developmental transitions\, or the reproducibility of shape across in dividuals and species? While genetics has revealed many of the molecular players involved\, the fundamental principles that govern the transform ation from cell to tissue to organism remain elusive. Developmental syst ems exhibit remarkable coordination across scales&mdash\;from gene expre ssion to mechanical forces to tissue geometry&mdash\;but how these level s interact to produce robust morphogenesis is still not well understood. This program will bring together experimentalists and theoreticians to work towards uncovering unifying rules of development and building bridg es between distinct biological systems. Central topics include how geome try and mechanical feedback influence growth and differentiation\; how c ell identities emerge from high-dimensional gene expression landscapes\; and how large-scale coordination is achieved in development\, regenerat ion\, and repair. By comparing independently evolved systems across the animal and plant kingdoms\, this program seeks to uncover shared strateg ies in developmental biology and foster interdisciplinary collaboration.

These events act as cosmic laborato ries allowing us to study the properties of high-density matter and the origin of heavy elements. Transients may even reveal particle physics b eyond the standard model in conditions that we cannot probe on Earth. Th e rapidly growing number and variety of observed EM transients now regul arly challenge our incomplete theoretical understanding of the transient sky. These limitations inhibit our ability to leverage transient obse rvations for high-energy and nuclear astrophysics. Despite significant i mprovements to the numerical accuracy and microphysics of numerical simu lations\, the impact of nuclear physics inputs\, approximate physical mo deling\, and the large range in spatial scales and timescales that need to be resolved remain major issues. This program will address these issu es with an interdisciplinary group of nuclear\, theoretical\, computatio nal physicists and astronomers as we prepare for a new era of EM discove ry and anticipated experiments on exotic nuclei.

The r ich molecular internal structures combined with long-range intermolecula r interactions and full controllability of quantum states at ultralow te mperature are both blessings and challenges. To explore the potential of ultracold molecules\, physics at very different energy\, time\, and len gth scales spanning many orders of magnitude must be addressed. Because of the complex and multiscale nature of this research field\, interdisci plinary and collaborative approaches are necessary to produce truly uniq ue practical opportunities for quantum science and technology\, from fun damental physics and testing predictions of the Standard Model\, through quantum-controlled chemical reactions\, to quantum computing and quantu m simulation.This program will explore investigations and applications o f ultracold molecules in all their intricacy and diversity.

Interactions between CRs and plasma exhibit p arallels across the interstellar (ISM)\, circumgalactic (CGM)\, and intr acluster (ICM) media. Advancing our understanding of these key but incom pletely understood processes\, particularly CR transport\, is essential for assessing the impact of CRs across these environments.This program w ill strengthen connections between distinct scientific communities study ing CRs across scales&mdash\;from the solar wind to galaxy clusters&mdas h\;with an emphasis on CR-plasma interactions. Although these communitie s are grounded in shared physical principles\, they have largely evolved in parallel. The program will promote dialogue between these groups to deepen understanding of CRs' role in shaping diverse astrophysical syste ms.The program will examine the following themes: CRs in turbulent plasm as: How do CR-driven instabilities\, wave damping\, and intermittent tur bulence regulate CR transport?CRs in the ISM: How do supernovae accelera te CRs\, and how do CRs shape ISM chemistry and star formation?CR feedba ck in galaxies and clusters: How do CRs from supernovae and black hole j ets drive galactic winds and shape the CGM and ICM? Astrophysical tests of CR transport: How can modeling of individual objects (supernovae\, st ar clusters\, radio filaments\, galaxies) constrain CR physics? Solar en ergetic particles: How do we model and constrain particle acceleration a nd solar wind-ISM interactions? Laboratory tests: How can laser plasma e xperiments inform CR propagation and acceleration models?

Using th is data to answer the biggest open questions in particle physics will re quire new ways of thinking about quantum field theory (QFT) and connecti ng it with data. While there has been tremendous recent progress in form al aspects of QFT\, much of it has been quite disconnected from experime nt. The study of detector operators\, most notably energy flux correlato rs\, has proven to be a remarkable exception. These observables\, which arise as direct theoretical models of collider experiments\, have played a crucial role in contemporary developments in formal QFT and gravity. Recently it has become possible to directly measure these observables at colliders\, leading to record precision extractions of Standard Model p arameters\, and measurements of properties of the quark gluon plasma. En ergy flow operators therefore provide a rare example of a vibrant and ti mely connection between real world phenomenology\, and advances in forma l QFT. This program will advance and build bridges between three areas: energy correlators in the collider frontier\, formal aspects of detector operators\, and their use in gravity and cosmology.

At the same time\, th ey have driven major developments in quantum field theory. This conferen ce will bring together theorists\, phenomenologists\, and experimentalis ts to advance the use of energy flow observables across collider physics and formal quantum field theory.

The influence‬‭ of‬‭ CRs‬‭ depends critically‬‭ on‬‭ the‬‭ physics‬‭ governing‬ CR transport. However\, this physics‬‭ remains‬‭ poorly‬‭ constrained\,‬‭ both‬‭ theoretically‬‭ and‬‭ observat ionally.On the theoretical front\, significant advances have been made i n particle-in-cell simulations of CR transport\, fluid simulations isola ting key CR processes\, and cosmological simulations incorporating physi cs-informed parameterizations of CR physics. From the observational pers pective\, new data from observatories operating across the full electrom agnetic spectrum will advance our understanding of the role of CRs in sh aping astrophysical systems. In the solar neighborhood\, data from the Parker Solar Probe and Solar Orbiter offer unique insights into particle acceleration and transport in the solar wind. Complementing these effor ts\, laboratory plasma experiments are now accessing regimes relevant to CR transport\, providing independent constraints.The next decade is poi sed to revolutionize our understanding of the impact of CRs across a bro ad spectrum of astrophysical environments\, from the solar wind to galax y clusters. This conference will explore similarities and analogies betw een different physical regimes and techniques and the growing interdisci plinary connections between the plasma physics\, turbulence\, solar wind \, interstellar medium\, star formation\, high-energy astrophysics\, gal axy formation\, and laboratory astrophysics communities.

Massive stars sha pe galaxies through ionizing radiation and chemical enrichment\, while t heir explosive ends inject energy and heavy elements into the interstell ar medium. Their remnants&mdash\;neutron stars and black holes&mdash\;ar e key sources of gravitational waves and high-energy phenomena. Yet\, cr ucial aspects of massive star evolution\, explosion mechanisms\, and rem nant formation remain elusive. We still lack a clear mapping between tra nsient phenomena and progenitor systems\, and a predictive framework for which stars produce which types of supernovae and which collapse direct ly to black holes. Recent advances have brought us to a pivotal moment. Time-domain surveys are capturing early-phase supernovae and revealing d ramatic late-stage behavior of progenitors. Gravitational-wave detection s are shedding light on compact object formation. Massive star surveys a re mapping the crucial role of binarity in massive star evolution and de ath. Upcoming facilities will open new discovery spaces in stellar evolu tion and explosion physics. During this program we hope to shed light on interconnected problems in the massive stars and supernovae by creating space for cross-disciplinary dialogue.
