Abstract: I discuss a holographic duality
between the SYK model in a double scaling limit and a 2d theory of
quantum cosmology called sine dilaton gravity.
Abstract: I will explore one of the most
profound open question in particle physics, focusing on some
exciting directions of my ongoing research activity: the strong CP
problem. I will begin with an overview of the strong CP problem,
highlighting...
Abstract: Global symmetry and anomaly have long
served as powerful organizing principles for understanding quantum
phases of matter in ground states. In this talk I will discuss
recent progress in extending these ideas to many-body mixed states.
I...
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...
