Fermiology of the 2D kagome lattice
Tue, Apr 19, 2022, 12:00 pm12:00 pm

Abstract:

The kagome lattice is a tiling of two-dimensional space comprised of corner-sharing triangles, having the same point symmetries as the honeycomb lattice (graphene) but a richer electronic structure. Recent theoretical developments suggest that the combination of magnetism, spin-orbit coupling, and geometric frustration in…

IAS HET Seminar | Amit Sever, Tel-Aviv University| “"Line Operators in Chern-Simons-Matter Theories and Bosonization in Three Dimensions” | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom
Mon, Apr 18, 2022, 2:30 pm2:30 pm

We study Chern-Simons theories at large N with either bosonic or fermionic matter in the fundamental representation. The most fundamental operators in these theories are mesonic line operators, the simplest example being Wilson lines ending on fundamentals. We classify the conformal line operators along an arbitrary smooth path as well as the…

HEP Seminar/ Cristian Peña/"Unlocking the CMS Experiment to Catch Long-lived Particles"
Mon, Apr 18, 2022, 2:00 pm2:00 pm

Enabling new long-lived particles (LLPs) searches at the LHC presents HEP research with unique opportunities. Introducing novel experimental techniques to identify and reconstruct LLPs will open up new possibilities for discoveries with striking signatures. I will present new long-lived particles searches, with a focus on the CMS Muon System…

Biophysics seminar: David Wolpert, Santa Fe Institute| Stochastic Thermodynamics of Distributed Systems
Mon, Apr 18, 2022, 12:30 pm12:30 pm

The new field of stochastic thermodynamics allows us to analyze the thermodynamic behavior of dynamic systems arbitrarily far from thermal equilibrium, and has produced many powerful theorems concerning phenomena completely absent in traditional statistical physics. However, to date stochastic thermodynamics has (mostly) been applied to systems…

PGI Spring Seminar Series|Dan Marrone|University of Arizona|"The Single Aperture Large Telescope for Universe Studies"
Mon, Apr 18, 2022, 12:30 pm12:30 pm

This year, NASA is beginning its search for a Probe-class ($1B) mission to fly in ~2032. This once-per-decade opportunity was endorsed by astro2020 as a way to achieve some of the science promised by the more complex and expensive far-infrared and X-ray missions that were prepared for the decadal survey. SALTUS, latin for leap, is a far…

Hamilton Colloquium Series, Salvatore Torquato, Princeton University, "Hyperuniform States of Matter"
Thu, Apr 14, 2022, 4:00 pm4:00 pm

The study of hyperuniform states of matter is an emerging multidisciplinary field, influencing and linking developments across the physical sciences, mathematics and biology. The hyperuniformity concept generalizes the traditional notion of long-range order to include not only all crystals and quasicrystals,…

HET Seminar | John Cardy, University of California, Berkeley | “TTbar-deformed modula” | Via Zoom
Mon, Apr 11, 2022, 2:30 pm2:30 pm

Certain objects of conformal field theory, for example partition functions on the rectangle and the torus, and one-point functions on the torus, are either invariant or transform simply under the modular group, properties which should be preserved under the TTbar deformation. The formulation and proof of this statement in fact extends to more…

Mon, Apr 11, 2022, 12:30 pm12:30 pm

Mechanical stability and shape changes of cells are determined by the dynamic interplay of four distinct cytoskeletal networks, made of actin filaments, microtubules, intermediate filaments and septins. These four filamentous systems contribute different structural and dynamical properties, enabling specific cellular…

IAS HET Seminar | Hong Liu, Massachusetts Institute of Technology| “"Emergent Times in Holography” | Via Zoom
Mon, Apr 4, 2022, 2:30 pm2:30 pm

We discuss emergent type III1 von Neumann algebraic structures in the large N limit of certain class of quantum field theories. We show that this is important for understanding various aspects of bulk physics in the AdS/CFT duality, including explicit boundary constructions of Kruskal-like time evolution in an eternal black hole, boundary…

Biophysics seminar: Sarah L. Keller, University of Washington| Phase-separating membranes of hungry yeast are tiny, living thermostats
Mon, Apr 4, 2022, 12:30 pm12:30 pm

Liquid-liquid phase separation of cell membranes exemplifies a biological system leveraging a physical concept to achieve a chemical end. Here, we show that yeast actively tune the transition temperature of their vacuole membranes to be close to the yeast's growth temperature, which implies that the membrane's proximity to the miscibility…

PGI Spring Seminar Series|Marc Casals|CBPF|"Stability Properties and Strong Cosmic Censorship for Rotating Black Hole Spacetimes"
Mon, Apr 4, 2022, 11:30 am11:30 am

Black holes in the Universe do not exist in isolation but, rather, they are surrounded by matter. It is therefore important to study the stability properties of black holes under matter field perturbations. In this talk we will discuss the stability properties under classical field perturbations of several rotating (Kerr) black hole spacetimes…

Hamilton Colloquium Series, Netta Engelhardt, MIT, "The Black Hole Information Paradox in the Age of Holographic Entanglement Entropy"
Thu, Mar 31, 2022, 4:00 pm4:00 pm

The black hole information paradox — whether information escapes an evaporating black hole or not — remains one of the greatest unsolved mysteries of theoretical physics. The apparent conflict between validity of semiclassical gravity at low energies and unitarity of quantum mechanics has long been expected…
