The zeta-instanton equation (also known as Witten's d-bar
equation) is a partial differential equation arising in
two-dimensional supersymmetric field theory. In this talk I will
review some of its properties and applications, from the...
Although today’s nuclear arsenals are not much in the news, they
pose enormous risks for all humanity. Moreover, many treaties that
have reduced the threat of nuclear weapons are now being abandoned,
and enormous resources are scheduled to be spent...
I will explain how the conformal bootstrap can be adapted
to place rigorous bounds on the spectra of automorphic forms on
locally symmetric spaces. A locally symmetric space is of the form
H\G/K, where G is a non-compact semisimple Lie group, K the...
GW170817 heralded the opening of multimessenger astronomy. To
predict or interpret gravitational wave sources, numerical
modeling, in particular, numerical relativity is a unique and
viable tool. In this talk, I will present the current status
of...
Abstract 1: The axion, motivated as a solution to the strong CP
problem, is also a viable dark matter candidate. If the initial
axion field is not homogenized by inflation, it can naturally
imprint large isocurvature fluctuations at extremely small...
I will introduce the topic of heavy multiquark states, with
special attention to the current theoretical and experimental
status. I will first review the available experimental information
and then discuss them in the context of the two most likely...
Magnetism has been in the forefront in our understandings of
protoplanetary disks (PPD) and planet formation. With the
prevalence of disk substructures, a major observational revolution
over the past few years, PPDs are now considered as “planet...
