Abstract: We focus on understanding how the
synchrotron emission morphology of astrophysical jet phenomena is
influenced by physical properties of the relativistic plasma within
the jet stream. To achieve this, we compare observational data in
multi...
Abstract: On-shell methods have found a new
application to local observables such as asymptotic radiation
fields and gravitational waveforms. While these observables are
invariant under small gauge transformations, they are known to
depend on a...
Abstract: Energy and information are
deeply connected in quantum field theory and quantum gravity. I
will describe an explicit protocol for an observer outside a
black hole to send in quantum information at zero energy cost. This
clarifies what sort...
Abstract: On general grounds one expects that
global symmetries are absent in quantum gravity. We discuss some
aspects of this issue, focusing on the recently proposed Swampland
Cobordism Conjecture, and related conjectures connected with...
Abstract: In this talk, I hope to describe
elements of proving a certain stable singularity formation result
for the Einstein--Euler system which is the topic of work in
progress with Jonathan Luk. I will first describe some of the
motivating...
Abstract: The appearance of chiral symmetry
from lattice fermions has been a non-trivial issue over many years.
We apply the idea of "emanant chiral symmetry" by Seiberg and Shao
to study the "emanant chiral supersymmetry" on the 1+1
dimensional...
Abstract: In this talk, we will discuss recent
advances in realizing programmable quantum systems using
neutral atom arrays excited into Rydberg states. These systems
allow control over several hundred qubits in two dimensions and the
exploration of...
Abstract: There is a surprising parallel between infinite
temperature DSSYK and large N QCD which I will explain. The
parallel may have much to tell us about the conjectured duality
between DSSYK and JT de Sitter space.
