Reparametrization modes provide a way of describing universal
physics of energy-momentum exchanges in CFTs. Drawing inspiration
from effective field theory methods and the SYK model, I will argue
that this perspective offers a useful computational...
I develop an effective theory which describes black holes with
quantum mechanical horizons that is valid at scales long compared
to the Schwarzschild radius but short compared to the lifetime of
the black hole. The formalism allows one to calculate...
Axions may be produced thermally inside the cores of neutron stars
(NSs), escape the stars due to their weak interactions with matter,
and subsequently convert into X-rays in the magnetic fields
surrounding the NSs. I will describe a hard X-ray...
I will discuss topological classification of gapped many-body
Hamiltonians and their ground states in dimension d. In general,
the problem is too hard as it includes diverse phenomena such as
degenerate ground states on the torus, anyons, and...
We will prove a conjecture [1] on upper bound of asymptotic gap in
dimension in unitary compact 2D CFT, proving it to be 1 using a
"extremal" function [2]. The notion of asymptotic gap can be
generalized to (h, \bar{h}) plane [3]. We will discuss...

I will introduce a new discrete transformation in quantum field
theory with Z2 1-form symmetry, with some applications to
boson/fermion dualities in (2+1)d.
This is based on the work https://arxiv.org/abs/1909.07383with
Shu-Heng Shao (IAS).
While the flat space two-body problem is integrable, the
generally-relativistic one is not starting at the next-to-leading
order.
In the appropriate classical limit, scattering amplitude-based
techniques can yield the classical interaction of massive...
