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: 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: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: 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: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: 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: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.
