Abstract: Post-inflationary QCD axion is an
attractive solution to the Strong CP problem because of the
possibility to uniquely predict the axion mass if axion makes up
all of dark matter. On the other hand, QCD axion models often
suffer from the so...
Abstract: String stars, or Horowitz-Polchinski
solutions, are string theory saddles with normalizable condensates
of thermal-winding strings. In the past, string stars were offered
as a possible description of stringy (Euclidean) black holes
in...
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...
