SUMMARY:Physics Colloquium: Daphne Klotsa
DESCRIPTION:Title: Making a Splash and Mixing It Up in Active Matter \nAbstract: Living matter\, such as biological tissue\, can be viewed as a nonequilibrium hierarchical assembly in which self-driven components consume energy to organize into increasingly complex structures across scales. These living\, or “active-matter\,” systems exhibit remarkable properties such as adaptability\, self-healing\, and self-organization\, raising fundamental questions about the underlying physics and whether similar functionality can be engineered in synthetic materials and other systems\, including robots and drug-delivery particles. In this talk\, I will focus on two classes of active systems that remain surprisingly unexplored: active matter in fluids with finite inertia and multicomponent active colloidal mixtures. I will present recent results showing novel emergent phase behavior and discuss their implications for materials design and technological applications.

SUMMARY:Physics Colloquium: Kenan Gundogdu
DESCRIPTION:Title: Rethinking Superfluorescence: A Window into Macroscopic Quantum Order \nAbstract: Macroscopic quantum coherence is typically associated with low temperatures\, where thermal fluctuations do not rapidly destroy phase correlations. In solids\, however\, electronic coherence is strongly influenced by lattice dynamics\, making it unclear how collective quantum states can persist at elevated temperatures.  \nIn this talk\, I will show how studies of superfluorescence provide a powerful window into the emergence of macroscopic coherence in condensed matter systems. By tracking the buildup of collective emission in lead-halide perovskites\, we find that superfluorescence does not originate from simple radiative synchronization of independent dipoles. Instead\, it reflects the formation of an underlying many-body excitonic state\, shaped by strong exciton–lattice interactions. Our results reveal a general mechanism in which lattice dynamics actively reorganize the electronic landscape\, enabling the emergence of coherent excitonic order at high temperatures. This perspective establishes superfluorescence as a diagnostic of nonequilibrium phase transitions and points to a broader principle for achieving macroscopic quantum coherence in strongly interacting systems. \n

SUMMARY:Physics Colloquium: Zhiyue Lu
DESCRIPTION:Title: Mathematical Foundation and Extension of Statistical Mechanics\nAbstract:  How can simple macroscopic laws emerge from the chaotic motion of astronomically many microscopic degrees of freedom? Statistical mechanics answers this question with a mathematical structure of striking simplicity\, built around entropy\, Boltzmann weights\, and free energy. In this colloquium\, I will revisit why that structure appears and why it is so universal. Using simple examples from probability\, gases\, and random walks\, I will argue that equilibrium statistical mechanics is fundamentally a theory of counting\, additivity\, and typicality. I will then show how the same logic can be extended beyond equilibrium by shifting attention from probabilities of states to probabilities of entire dynamical trajectories. This broader viewpoint provides a natural language for irreversibility\, entropy production\, and modern fluctuation relations. The emphasis will be on concepts rather than technical detail\, with the goal of giving a broad physics audience a unified picture of how statistical mechanics is founded and how it continues to evolve.

SUMMARY:Physics Colloquium: Brad Barlow
DESCRIPTION:Title: Gaia in Technicolor: Mapping Stellar Variability Through H-R Diagram Motions \nAbstract: Most people think of the famous H-R diagram in stellar astrophysics as being essentially static over human lifetimes\, changing only on timescales of millions or billions of years. However\, some pulsating stars and eclipsing binaries exhibit photometric and color variations strong enough that their positions in the H-R diagram actually oscillate on much shorter timescales than their evolutionary timescales. The European Space Agency’s Gaia spacecraft makes the detection of these motions possible for millions of stars for the first time. By combining photometry from its G (green)\, BP (blue)\, and RP (red) filters\, we can track individual stars’ positions in the H-R diagram across 50-100 different epochs throughout the lifetime of the Gaia mission. Here we present results showing that we can not only detect H-R diagram motions in millions of objects but also use the patterns of these motions to discover and classify new pulsators and binaries. In some cases\, this approach has revealed previously unknown types of variables.

SUMMARY:Physics Colloquium: Patrick Charbonneau
DESCRIPTION:Title: The Gendered History of Quantum Physics \nAbstract: The book Women in the History of Quantum Physics: Beyond Knabenphysik presents original analyses of the lives and work of sixteen women who\, throughout the twentieth century\, from various locations and in diverse ways\, participated in the development of quantum physics. By focusing on lesser-known figures and introducing a gender perspective to historical studies of physics — on the centennial of quantum mechanics — the interdisciplinary work aims to challenge the conventional all-male narratives that often reinforce the masculine image of the field. From these richly detailed microhistories\, several themes emerge\, offering insights into the historically persistent gendered dynamics of physics research. This talk highlights\, in particular\, the contributions of Hertha Sponer and Elizabeth Monroe\, pioneers in bringing quantum mechanics to chemistry.

SUMMARY:CMB Seminar: Scott Franklin
DESCRIPTION:Title: Geometrically Cohesive Granular Materials: Structure\, Permeability and Porosity \nAbstract: \nGeometrically cohesive granular materials (GCGMs) are granular materials whose shape allows for particle entanglement that can result in extreme rigidity (c.f. bird nests\, beaver dams and entangled clothes hangers). In this talk I’ll first review some surprising rheological features of GCGMs that arise from the collective particle interactions and introduce Super-ellipse Sector Particles\, a construct that can parameterize a wide variety of particle shapes\, including (pictured below) round and sickle-shaped blood cells\, U-shaped staples\, colloidal nanopods\, long\, thin rods and bent-core liquid crystals. \nI’ll then describe new experiments on fluid flow through packings of large aspect-ratio granular rods which have significantly higher porosity\, permeability and stability than those of ordinary\, round granular materials. Practically\, this allows rods used as proppant in hydraulic fracture to increase natural gas recovery rates by 10-13% and virtually eliminate the need for post-recovery processing to filter out unwanted sediment. We measure the permeability and porosity of rod packings for a variety of particle aspect ratios and container sizes and\, separately\, use refractive index matched (RIM) tomography to image the full 3d packing. This allows us to calculate not only bulk porosity but the size distribution for both voids and throats\, where sediment clogging is most likely. We calculate the shortest connected paths across the pile as a function of intruder size and use this to predict packing filtration properties.

SUMMARY:Physics Colloquium: Scott Franklin
DESCRIPTION:Title: Empathy in Physics Classrooms and other Academic Spaces \nAbstract: This talk explores the role of empathy — the ability to understand and share feelings\, thoughts\, and experiences of another — in physics classrooms and other academic spaces. Specifically\, we ask: 1) how do faculty conceptualize empathy and its place in the classroom; 2) how do faculty develop empathetic understanding for students; and 3) how and why do faculty intentionally share information about themselves to build this understanding. Semi-structured interviews of 19 physics faculty of varying ranks and experience reveal common themes in interactions with students. From these we develop a theoretical model that includes both cognitive empathy—recognizing and understanding another person’s perspective—and emotional/affective empathy —experiencing and responding to another person’s emotions. The model reveals key mediators that lead one from noticing to empathy to action and moderators that influence the strength of this development. We identify a new mediator for cognitive empathy\, Reflective Witnessing\, in which faculty reflect not only on a student’s experience but their role in that experience. Different faculty approaches to empathy are also manifested in their approach to sharing information about their personal identities These are summarized in four personas that illustrate the different motivations faculty have for sharing or concealing personal information. I’ll conclude with directions for future research as well as an opinion on the need to ground student support programs in an understanding of the individual.

SUMMARY:TNT Colloquium: Jonah Miller
DESCRIPTION:Title: Neutron Star Mergers as a Laboratory for Neutrino Physics: Neutrino Oscillations\, Neutrino-matter Interactions\, and Neutrino Advection \nAbstract: The 2017 detection of the in-spiral and merger of two neutron stars was a landmark discovery in astrophysics. Through a wealth of multi-messenger data\, we now know that the merger of these ultracompact stellar remnants is a central engine of short gamma ray bursts and a site of r-process nucleosynthesis\, where the heaviest elements in our universe are formed. The radioactive decay of unstable heavy elements produced in such mergers powers an optical and infra-red transient: The kilonova. \nThese merger events and their aftermath depend sensitively on the behavior of neutrinos\, which control the abundance of free neutrons available for the r-process. In this talk\, I discuss how and why this problem is a significant modeling challenge for the community\, present high-fidelity simulations of post-neutron-star merger disks\, and discuss the impacts of various processes\, including the neutrino fast-flavor instability\, on observables\, such as kilonova and nucleosynthetic yields.

SUMMARY:Physics Colloquium: Claudia Fracchiolla
DESCRIPTION:Title: Public Engagement as a Physics Practice: Identity\, Community\, and Building the Infrastructure for Impact \nAbstract: Public engagement or\, as it is more commonly known\, “outreach” often lives at the periphery of physics departments\, something some do in their “free” time. Yet many physicists and students facilitate informal programs. But what do we know about how these efforts work\, what they produce\, what they require to be effective and equitable and what they do to the people who facilitate them? \nIn this talk\, I synthesize research linking public engagement to identity development in physics and to the structures that sustain informal programs. I show how facilitating engagement can foster discipline-based identity\, and how this identity development matters not only for participants\, but also for facilitators\, with implications for physics culture and student retention. I then connect these mechanisms to research mapping and characterizing informal physics programs\, showing that outcomes hinge less on any single activity than on the relationships\, roles\, and organizational structures that support participation over time. I close this research synthesis by translating it into practical design principles that shift engagement from one-way outreach toward bidirectional\, community-responsive practice. \nFinally\, I share how these insights inform the work at the American Physical Society\, where we build structures that help physicists engage and keep engaging\, through efforts such as JNIPER\, the Science Trust Project\, and PhysicsQuest.

SUMMARY:Nuclear Theory Seminar: Emilie Huffman
DESCRIPTION:Title: Generalizing deconfined criticality to 3d N-flavor SU(2) quantum chromodynamics on the fuzzy sphere \nAbstract:  The fuzzy sphere formalism is a recently introduced powerful lens to probe critical behavior and find clear numerical signatures of conformal symmetry. After introducing the technique\, we use it to investigate a candidate for SU(2) QCD with N fermions and a global symmetry which is a possible effective description of the deconfined quantum critical point (DQCP)—a phase transition beyond the Landau paradigm. Employing quantum Monte Carlo simulations of the generalized models\, we probe the conformal window of the gauge theories\, with the fuzzy sphere formalism significantly reducing finite-size-effects.

SUMMARY:Physics Colloquium: Greg Gbur
DESCRIPTION:Title: Invisibility: The History and Science of How Not To Be Seen \nAbstract: The idea that it might be possible to make a perfect invisibility cloak was a frequent topic in the news and the scientific literature over the past two decades. The subject of invisibility physics\, however\, has a history that stretches back well over a century. In this talk\, we will look at the origins of invisibility physics\, from the first attempts of science fiction writers to explain the impossible\, all the way to modern approaches. We will see how concepts of invisibility have touched many aspects of physics through the years\, even when it wasn’t directly recognized as such.

SUMMARY:TNT Seminar: Mia Kumamoto
DESCRIPTION:Title: Pion Mass Dependence in Chiral EFT and the QCD Axion \nAbstract:  \nQCD and effective field theory together put low energy nuclear physics on solid theoretical footing to calculate observables with some confidence\, but open questions remain.  Two related questions are why QCD seems not to violate CP and how the properties of nuclear matter depend on the light quark masses (or equivalently the pion mass).  The classic solution to the former problem is to invoke a new light field\, the QCD axion\, a well-motivated dark matter candidate which a diverse experimental campaign is currently searching for.  Neutron stars can also probe the QCD axion parameter space if nuclear matter becomes more attractive at reduced pion mass via the formation of an axion condensate.  Answering the question of whether an axion with a mass at the QCD prediction could condense in neutron stars hinges on a number of fundamental questions in nuclear physics\, including the properties of three nucleon forces\, the importance of light resonances neglected in chiral EFT\, fine tuning in s-wave scattering\, and at what density chiral symmetry restoration occurs in cold nuclear matter.  In this talk\, I will present our current research on pion mass dependence in chiral EFT\, possible observable signatures in neutron stars\, and what the study of pion mass dependence can teach us about extant theoretical problems in low energy nuclear physics.

SUMMARY:Physics Colloquium: Michael Shull
DESCRIPTION:Title: Ionization Sources of the Local Interstellar Clouds \nAbstract: The structure of the local interstellar clouds is influenced by stellar ionizing sources that shaped it dynamically and thermally over the last 5 million years. The dominant sources include two massive B-type stars\, currently at distances of 124 and 151 pc in the Canis Majoris constellation\, and three hot white dwarfs (at 52\, 60\, and 77 pc). Our solar system is surrounded by wispy interstellar gas clouds\, 30 lt yr in extent\, which shield us from most of this ionizing radiation. However\, 4.4 million years ago\, those two B-stars stars passed within 30–35 light years of the Sun\, leaving behind a trail of ionized and photoelectrically heated gas. Additional ionizing photons come from the Local Hot Bubble\, a glow of million-degree plasma generated by shock waves from past supernova explosions in the nearby Scorpius – Centaurus OB association. The unusual level of ionized hydrogen and helium entering the heliosphere likely reflects these sources\, altered by the propagation and filtering of EUV and X-ray radiation through the clouds.

SUMMARY:CMB Seminar: Brian Kuhlman
DESCRIPTION:Title: De novo protein design with multi-objective fitness functions \nAbstract: We have developed a protein design pipeline\, called EvoPro\, that uses iterative rounds of deep learning-based structure prediction and sequence optimization to evolve protein sequences for prespecified design goals. Two design projects will be described that make use of EvoPro: the creation of a set of de novo proteins where binding of protein A to protein B induces a conformational change in protein B that allows binding to protein C\, and the design of protein-based vaccines for dengue virus.

SUMMARY:Physics Colloquium:Henning Back
DESCRIPTION:Title: Advancing Ultra-Sensitive Radiation Detection: Applications of Rare Event Physics to Global Security \nAbstract: Addressing global security challenges requires enhanced radiation detection capabilities to meet the needs of organizations such as the IAEA\, CTBTO\, and the U.S. Government. Key priorities include the accurate determination of radionuclide concentrations in environmental samples with improved speed\, sensitivity\, and adaptability to diverse sample profiles\, such as aged or minute samples. Advances in rare-event physics technologies\, originally developed for dark matter searches and neutrino experiments\, are proving critical in achieving the ultra-sensitive thresholds needed for these missions. This presentation will explore the application of next-generation groundwater age-dating methodologies as a case study for leveraging rare-event physics technologies. Additionally\, I will introduce the multidisciplinary Facility for Underground Science and Engineering (FUSE) under development at Savannah River National Laboratory\, highlighting its unique underground laboratory environment optimized for minimizing background radiation and enabling cutting-edge detection research.
