Abstract: Tidal deformabilities serve as
an effective tool to study the structures of compact
objects. In the first part of the talk, I will present how the
worldline effective field theory (EFT) can be applied to examine
the tidal responses of...
Abstract: Inflation, the theory describing a
period of exponential superluminal expansion in the early universe,
is both a proposed solution to the large-scale structure we see in
our night sky and a mystery of which we have little
experimental...
Abstract: In this talk we use
integrability data to bootstrap correlation functions of planar
maximally supersymmetric Yang- Mills theory, focusing on
four-point correlation function of stress-tensor. First,
we start by demonstrating why the...
Abstract: I will present a case for the
striking resemblance between bubbles of anti-de Sitter (AdS) within
Minkowski spacetime and black holes. These solutions of
Einstein’s equations are motivated by high-energy physics and lack
horizons. We will...
Abstract: In this talk I will discuss
holographic duals of topological operators. At low energy
sugra, they can be realized by Page charge associated to Gauss law
constraints. In the UV string theory, topological operators can be
characterized by...
Abstract: I will compare the gravitational
sectors of two 10d heterotic string theories, with E8 x E8 and
Spin(32)/$Z_2$ gauge groups, and show that they differ by a subtle
$Z_3$-valued topological term. I also discuss its relation to
the...
Abstract: Quantum critical points usually
separate two distinct phases of matter. Here I will discuss a class
of "unnecessary" quantum critical points that lie within a single
phase of matter (much like the liquid-gas transition, except that
they...
Abstract: Although solutions to
Teukolsky’s radial equation play a key role in black hole
perturbation theory, there are limitations in our understanding
that obscure our practical use of e.g. quasi-normal mode overtone
solutions. Towards...
