Abstract: We discuss relaxation solutions to
the dark matter - baryon coincidence problem in the context of QCD
axion dark matter. In relaxation solutions, a moduli dynamically
adjusts the mass of dark matter and baryons until their energy
densities...
Abstract: Love numbers quantify how compact objects deform under
external tidal fields. They are key gravitational wave observables
and provide a direct probe of compact-object structure. At linear
order, black hole (BH) Love numbers vanish - a...
Abstract: In large N theories with a gravity
dual, generic heavy operators should be dual to black holes in the
bulk. The microscopic details of such operators should then be
irrelevant in the low energy theory. We look for such universality
in the...
Abstract: In this talk, I will explore a
variety of 1+1d lattice models exhibiting anti-unitary symmetries
that simultaneously reflect space and reverse time. These
symmetries can be anomalous, leading to Lieb-Schultz-Mattis-type
constraints that...
Abstract: QCD remains elusive in the
high-energy, small-angle regime where all known methods break down.
This regime governs total and differential cross-sections and is
tied to the long-standing puzzle of the Pomeron, a trajectory with
vacuum...
Abstract: In recent years, low-dimensional
models of gravity have been useful toy models to study deep puzzles
of quantum gravity like the black hole information paradox. For
two-dimensional JT gravity, a new duality was discovered: JT
gravity is...
Abstract: I will discuss the path integral of
pure 3D gravity on a finite region of spacetime, with boundary
conditions that fix dihedral angles or geodesic lengths. This
amplitude calculates corrections to the Gaussian statistics of
OPE...
Abstract: Event Horizon Telescope (EHT)
observations of M87* provide a means of constraining parameters of
both the black hole and its surrounding plasma. However, intrinsic
variability of the emitting material introduces a major source
of...
Abstract: I will talk about the adiabatic
cycles of one-dimensional gapped Hamiltonians with non-invertible
symmetry. Using quasiadiabatic evolution and the results of gapped
phase classification, the adiabatic cycles can be classified by
the...
