SUMMARY:CMB Seminar: Luis Zambrano
DESCRIPTION:Title: A Generalized Critical State Approach for Granular Rheology and Impact Loading\nAbstract: The dynamics of dense granular-fluid mixtures\, such as those occurring in landslides and debris flows\, embody a complex interplay and transition between solid mechanics and fluid dynamics. Despite major advances in large-deformation analysis\, geotechnical modeling remains largely governed by strain-independent critical state soil mechanics\, even though substantial evidence indicates that granular rheologies more accurately describe the constitutive behavior of materials undergoing flow and large strains.\nIn this seminar\, I will present a constitutive framework that extends the critical state concept by incorporating principles from particle kinetic theory and granular rheology. This generalized critical state formulation captures the continuum of granular behavior beyond the solid and dense flow regimes. Using numerical simulations of impact triaxial tests\, the framework successfully predicts enhanced peak deviatoric stresses and pronounced dilation at small strains under high-velocity impact loading. These results demonstrate the potential of extended critical state models to describe strain-rate–dependent rheologies and hydromechanical coupling in granular-fluid mixtures. \n

SUMMARY:Physics Colloquium: Michael Rubinstein
DESCRIPTION:Michael Rubinstein\, Duke University \nTitle: The Loops of Life \nAbstract: In mammalian cells\, the cohesin protein complex is believed to regulate chromatin during interphase through active loop extrusion\, in which dynamic loops are formed by cohesin translocating along chromatin. We developed a theoretical model that quantifies how key parameters\, including cohesin residence time on chromatin\, extrusion velocity\, and the number density of chromatin-bound cohesins\, regulate genomic contacts. The model describes chromatin contact probabilities and predicts that loop formation probability is a nonmonotonic function of loop length. Our theory demonstrates that active loop extrusion causes the apparent fractal dimension of chromatin to cross over between two and four at contour lengths on the order of 30 kilo-base pairs. This work provides a theoretical basis for the compact organization of interphase chromatin explaining the physical reason for the segregation of topologically associated domains and suppression of chromatin entanglements by up to a factor of 50 which contributes to efficient gene regulation by distal elements such as enhancers or silencers.

SUMMARY:Physics Colloquium: Vashan Wright
DESCRIPTION:Vashan Wright\, UCSD / Scripps Institute of Geophysics and Planetary Physics \nSearching for Evidence of Water in the Martian Crust \nLiquid water existed on Mars in rivers\, lakes\, and as groundwater. The water is hypothesized to have subsequently been buried as ice or liquid water\, incorporated in minerals\, or lost to space. Geophysical measurements have the potential to test the first of these three hypotheses because water affects the physical properties of rocks\, such as elastic moduli and bulk density. We use a forward modeling approach and a Markov Chain Monte Carlo inversion scheme to identify combinations of rock type\, water distribution\, porosity\, and pore shape consistent with the seismic velocities and gravity within 50 km of the InSight lander on Mars. The shear Vs and compression Vp wave velocities within the upper 300 m are consistent with a crust composed of minimally cemented (< 2 % of the pores) sediments. Fractured rocks at this depth could host ice within 20% of the pore space. Vs within the upper 8 km of the crust are too low for a fully ice-saturated cryosphere. Using Vs\, lithology\, and gravity-derived bulk density data\, we find that the lower crust (11.5-22 km below the surface) beneath InSight is mafic and highly porous or felsic and less porous. The addition of Vp data leads to the conclusion that a lower crust composed of igneous rock with thin fractures filled with liquid water can explain the existing data\, though available seismic attenuation data provide a challenge to these findings. Our results have implications for understanding Mars’ water cycle from the Noachian to the present\, determining the fates of past surface water\, searching for past or extant life\, and assessing in-situ resource utilization for future missions.

SUMMARY:Physics Colloquium: José Alvarado
DESCRIPTION:Title: Adaptability Through Control in Robotic and Active Systems \nAbstract: One of the hallmarks of adaptive matter is the ability to sense and respond to the environment. How can we engineer soft matter systems to exhibit such behavior? In this talk\, I will present our recent findings on systems driven by centimeter-scale actuators (electric motors) and nanometer-scale actuators (myosin motors)\, using methods from control theory to either design function or probe system properties. Such control-theoretical approaches are often exploited in engineering applications. I will instead emphasize how control in active and robotic systems can help physicists better understand information processing\, orchestration of function\, and adaptability in living systems. \nHost: Julio Monti Belmonte

SUMMARY:CMB Seminar: Lucia Stein-Montalvo
DESCRIPTION:Title: Shape-shifting mechanics for adaptive cities  \nAbstract: Rapid urbanization is intertwined with urgent\, climate change related threats to human well-being and environmental health. Meanwhile\, much of our built environment relies on static structures\, which require substantial energy input for cooling and other interventions — resources often unavailable to much of the global population. Addressing these challenges requires sustainable designs\, that respond to changing environmental conditions to maintain the comfort and safety of urban inhabitants. Shape-shifting\, slender structures offer an approach by guiding the design of morphing systems\, that can regulate the surrounding environment. Here\, we present two examples where fundamental mechanics insights\, gained through experiments and simulations\, enable the development of interactive\, meter-scale prototypes that modulate wind and/or light. Specifically\, we demonstrate how controllably buckling structures based on kirigami (“cut paper”) can improve ventilation in urban spaces\, and how circumferential buckling of confined\, thin sheets forms the basis of a testbed for adaptive shading and human-architecture interaction.

SUMMARY:CMB Seminar: Artem Rumyantsev
DESCRIPTION:Title: Conformations of Polyampholytic Disordered Proteins: Does Nature Use Multicriticality \nAbstract: Recent advancements in understanding intracellular organization have been significantly attributed to the application of polymer physics methods. A notable example is the formation of membraneless organelles from intrinsically disordered proteins (IDPs)\, which can be described as liquid-liquid phase separation in a polyampholyte (PA) solution. This inspired us to apply the similar theoretical framework to single-chain PAs. We constructed a comprehensive scaling diagram of PA conformations\, covering a broad range of salt concentrations and charge imbalances—from net-neutral PAs to polyelectrolytes carrying charges of only one sign. Theoretically predicted scaling laws were quantitatively confirmed through simulations.\nThe most intriguing feature of the conformational diagram is the presence of the point where regimes of swollen chains\, globules\, and necklaces meet. It is analogous to the multicritical Lifshitz point in macroscopic systems of ionic polymers (e.g. solutions and coacervates)\, where disordered\, homogeneous ordered\, and periodically modulated ordered phases coexist. Although our scaling estimates are inevitably approximate\, they demonstrate that at intracellular salt concentration\, the composition of real IDPs places them near this (single-chain analog of) Lifshitz point. We hypothesize that these strong\, critical fluctuations in IDPs’ shape and size provide them with the high conformational heterogeneity and susceptibility necessary for their functions in signaling and regulation. A related question is whether the IDP composition could have been evolutionarily tuned for this purpose. In other words\, does nature intentionally employ multicriticality?

SUMMARY:CMB Seminar: Nathan Ennist
DESCRIPTION:Title:  Engineering new proteins for enhanced photosynthesis \nAbstract: Plants\, green algae\, and cyanobacteria power the biosphere using oxygenic photosynthesis to oxidize water to oxygen and liberate high-energy electrons for carbon fixation.  Despite its evolutionary success\, oxygenic photosynthesis has a low overall efficiency.  It fails to make use of the abundant energy in the near-infrared region of the solar spectrum\, and it loses energy to thermalization and inefficient charge separation.   We leverage recent developments in AI methods for protein design such as AlphaFold\, RFdiffusion\, and ProteinMPNN to engineer new high-efficiency photosystems that control light-activated electron tunneling\, use excitonic coupling to tune spectroscopic properties of chromophores\, assemble novel metal clusters\, and catalyze redox reactions.  We characterize the designs using spectroscopy\, electrochemistry\, cryo-electron microscopy\, and X-ray crystallography.  This research project may lead to enhanced photosynthesis for improved production of renewable solar fuels\, sustainable ammonia for fertilizer\, and faster-growing crops for food.

SUMMARY:CMB Seminar: Chrystal Starbird
DESCRIPTION:Title: Investigating Multimodal Activation of Cellular Signaling Pathways Through Lipids \nAbstract: Key signaling molecules\, receptor tyrosine kinases (RTKs) are a clinically important family of receptors that act as key regulators of a wide range of biological functions and as such\, play a role in the development of various diseases. All RTKs are membrane proteins that share a single-pass transmembrane helix that links and extracellular domain with an intracellular kinase domain. Structurally\, how a single helix promotes the large diversity of signaling processes mediated by RTKs has long been a question of interest\, and classically\, RTKs are considered to be activated by ligand-induced dimerization. However\, in recent years it has become clear that RTKs utilize a wide variety of mechanisms to promote activation and signaling and a subfamily of RTKs\, TAM receptors\, appear to have unique requirements for activation and offer a great system to study some of these alternative mechanisms. Preliminary data from my lab suggests that TAM receptors are capable of forming ligand-independent dimers and may form high order oligomers\, or clusters\, during activation that are driven by interactions with membrane lipids. My lab works to gain new insights from cellular and structural studies into the dependence of TAM receptors on the membrane lipid\, phosphatidylserine\, in the activation of TAM receptors and other important drivers of cellular phagocytosis during signaling. \nHost: Christa Baker

SUMMARY:Physics Colloquium: Matthew Green
DESCRIPTION:Title: COHERENT Elastic Neutrino-Nucleus Scattering at the SNS \nAbstract: \nCoherent Elastic Neutrino-Nucleus Scattering (CEvNS) is a low-energy neutrino scattering process predicted as a consequence of the weak neutral current in 1974. \nDespite the theoretically-understood\, relatively large cross-section\, until recently the process remained undetected due to the daunting technical challenges involved (low-threshold nuclear recoil detection\, intense neutrino sources / large target masses\, and low backgrounds). The COHERENT Collaboration formed with the aim to measure CEvNS and to use it as a tool to search for physics beyond the standard model by employing state-of-the-art detector technology at Oak Ridge National Laboratory’s (ORNL) Spallation Neutron Source (SNS). In August 2017 COHERENT reported the first-ever observation of CEvNS in a CSI[Na] scintillation detector; this measurement has been followed by subsequent measurements in a liquid argon scintillation detector and in an array of germanium semiconductor detectors. Matthew Green has led COHERENT’s efforts to measure CEvNS in high-purity germanium (HPGe) detectors. This talk will give an overview of the CEvNS process\, the physics capabilities of CEvNS searches\, and an update on COHERENT’s CEvNS measurement efforts.

SUMMARY:Physics Colloquium: Andrey Tarasov
DESCRIPTION:Title: Factorization and perturbative QCD in the era of Electron-Ion Collider \nAbstract: The future Electron-Ion Collider (EIC) at the Brookhaven National Laboratory is a uniquely capable machine which is designed to address some of the most profound questions about the properties of nuclear matter. To unravel the rich structure of hadrons\, the EIC will provide precision imaging of a strongly bounded many-body parton system inside the hadrons. The dynamics of this system give rise to such fundamental properties of the hadron as spin and mass. The strong QCD (Quantum Chromodynamics) medium inside the hadron can be probed in the high-energy scattering experiments within the QCD factorization approach through a subtle interplay between its perturbative and non-perturbative components. I will demonstrate that for many observables at EIC\, such as the search of the saturation\, three-dimensional imaging of the hadron\, the chiral anomaly effects etc.\, an adequate description of this interplay requires development of novel methods and calculation techniques. I will introduce a general framework for such techniques which is based on application of the background field method. I will show how implementation of such methods allows us to systematically understand the properties of the dense QCD medium inside the hadron and put the light on the origin of its most fundamental properties.

SUMMARY:Physics Colloquium: Julio Monti Belmonte
DESCRIPTION:  \nTitle: Mesoscale Computational Biophysics: From Cytoskeleton Percolation to Tissue Mechanics \nAbstract: \nBiophysics is an interdisciplinary field that combines physics\, biology\, chemistry\, and mathematics to understand complex problems in living systems. While it is best known for addressing molecular-level problems\, its range of applicability also extends to the cell and tissue scales\, often borrowing concepts from soft and active matter. In this talk\, I will highlight two recent stories from my group\, where we used theoretical and computational approaches to understand problems at these higher length scales. In the first story (at the cell level)\, I will introduce the problem of connectivity in cytoskeletal systems—a network of filaments and motors that drive the generation and transmission of forces in cells—and how a simple theoretical approach can be used to predict network outcomes in both in vivo and in vitro systems. In the second story (at the tissue level)\, I will present results from a new microscopy technique (bio-Brillouin) that revealed rapid changes in cell material properties during tissue development (on the order of minutes)\, and a physical model that demonstrates how these dynamic changes in both space and time optimize morphogenesis. \nAdd team comment
