Abstract: In astrophysical fluid dynamics, stars are considered as isolated fluid masses subject to self-gravity. A classical model of a self-gravitating Newtonian star is given by the gravitational Euler- Poisson system, while a relativistic star...

Abstract: The Fractional Quantum Hall effect is one of the most fundamental phenomena of quantum physics. Under a very large magnetic field, and at fractional filling of a Landau level, when electrons are “supposed” (by simple band theory) to form a...

Abstract: Abstract: In this talk, I will review the underlying algebraic structure of de Sitter quasinormal modes (QNMs), and the relation between QNMs and one-loop quantum corrections to dS entropy. I will explain how this picture extends to Anti...

Abstract: I will begin by reviewing gauge/string duality, and in particular the motivations for understanding this duality better in the case of weakly coupled gauge theories. I will then discuss work in progress on two approaches to understanding...

Abstract: LUX-ZEPLIN (LZ) is a direct detection dark matter experiment currently being operated at the Sanford Underground Research Facility (SURF) in Lead, South Dakota. The experiment utilizes a dual phase time projection chamber (TPC)  to...

Abstract: The Kaluza-Klein theories represent the classical mathematical approach to the unification of general relativity with electromagnetism and more generally with gauge fields. In these theories, general relativity is considered in 1+3+d...

Abstract: Machine learning is now a part of physics for the foreseeable future, but many deep learning tools, architectures, and algorithms are imported from industry to physics with minimal modifications. Does physics really need all of these fancy...

Abstract: I will review why current large language models cannot deal with algorithmic problems without using external tools. After explaining the transformer architecture from a point of view of a physicist, I will highlight the increasing role of...

Abstract: M- and F-theory compactifications with ADE singularities give rise to non-abelian ADE gauge symmetries. The physical explanation for this phenomenon involves M2-branes wrapped on vanishing cycles. We consider an alternative approach which...
