Hamilton Colloquium Series, Kaushik Bhattacharya, Caltech, "Liquid Crystals Meet Elastomers"", Jadwin A-10
Tue, Dec 13, 2022, 4:00 pm5:00 pm

Liquid crystal elastomers are rubbery solids with liquid crystal mesogens incorporated into their polymer chains.  These solids combine the entropic elasticity of rubber with the orientational phase transitions of liquid crystals.  The deformation and orientational order are coupled, giving rise to a rich variety of phenomena…

Harmonic Analysis of the Stochastic Gravitational Wave Background - Kim Boddy - University of Texas
Tue, Dec 13, 2022, 4:00 pm5:30 pm

Abstract: A stochastic gravitational wave background (SGWB) is expected to be generated from a population of unresolved sources and potentially from early Universe processes. In the nHz band, supermassive black hole binaries generate a SGWB, and there have been hints that a detection of the SGWB by pulsar timing arrays (PTAs) may be on the…

Biophysics Seminar: Na Ji, UC Berkeley| Imaging the brain at high spatiotemporal resolution
Mon, Dec 12, 2022, 12:30 pm1:30 pm

To understand computation in the brain, one needs to understand the input-output relationships for neural circuits and the anatomical and functional properties of individual neurons therein. Optical microscopy has emerged as an ideal tool in this quest, as it is capable of recording the activity of…

PGI Seminar Series Fall 2022|Georgios Mavrogiannis|Rutgers University "Relatively Non-Degenerate Estimates on Kerr de Sitter Spacetimes"
Mon, Dec 12, 2022, 12:30 pm1:30 pm

"We will start discussing a new method of how to prove exponential decay for the solutions of the wave equation on a Schwarzschild de Sitter black hole spacetime by exploiting a novel "relatively non-degenerate" estimate. This estimate does not degenerate at trapping. The main ingredient in proving this estimate is to commute with a novel…

Simulatable models of Quantum Criticality in Heavy Fermion Systems - Tarun Grover
Tue, Dec 6, 2022, 12:00 pm1:00 pm

Abstract: The fermion sign problem tends to stymie exploration of
highly entangled phases of fermions, such as those relevant for heavy
fermion quantum criticality. In this talk, I will present recent
progress in simulating Fermi and non-Fermi liquids in the context of
Kondo lattice systems. One of the new ideas is…

HET Seminar |Shu-Heng Shao(Stonybrook) | “ Symmetry Lost and Found” | PCTS & Zoom
Fri, Dec 2, 2022, 1:45 pm1:45 pm

In massless QED, we find that the classical U(1) axial symmetry is not completely broken by the Adler-Bell-Jackiw anomaly. Rather, it is resurrected as a generalized global symmetry labeled by the rational numbers. Intuitively, this new global symmetry in QED is a composition of the naive axial rotation and a fractional quantum Hall state…

Hamilton Colloquium Series, Roland Bauerschmidt, University of Cambridge"Different Perspectives in Statistical Physics" Jadwin A-10
Thu, Dec 1, 2022, 4:00 pm5:00 pm

The use of different perspectives on a problem is a very powerful principle in statistical physics, and has been especially important in mathematical physics. I will illustrate this theme with old and recent applications. These include the interpretation of QFTs at imaginary time as statistical fields, the relation of statistical fields to…

Dark Cosmo Seminar: Deep learning as a general framework to unveil the nature of dark matter
Tue, Nov 29, 2022, 4:00 pm5:30 pm

The formation and evolution of structures in the Universe is expected to be affected by the nature and properties of dark matter. For this reason, we can made use of cosmological and astrophysical observations to learn about dark matter. Unfortunately, there are multiple intrinsic complications associated to the search of those signatures: 1)…

Condensed Matter Seminar - Engineering topological phases with a superlattice potential
Tue, Nov 29, 2022, 12:00 pm1:30 pm

Abstract: We propose an externally imposed superlattice potential as a platform for manipulating topological phases, which has both advantages and disadvantages compared to a moire superlattice. In the first example, we apply the superlattice potential to the 2D surface of a 3D topological insulator. The superlattice potential creates tunable…

HET Seminar |Monica Kang (Caltech) | “Nonperturbative gravity corrections to bulk reconstruction” | PCTS & Zoom
Mon, Nov 28, 2022, 2:30 pm2:30 pm

I will first motivate the benefits on taking the algebraic approach to understand AdS/CFT and how an algebra of local operators of QFT has knowledge of a spacetime region. Utilizing both operator algebras and quantum information theory, I will explain a new framework for understanding nonperturbative gravitational aspects of bulk reconstruction…
