Abstract: More than twenty years ago, in
an experiment at Brookhaven National Laboratory, physicists
detected what seemed to be a discrepancy between measurements of
the muon’s magnetic moment and theoretical calculations of what
that measurement...
Abstract: I will discuss the reasoning behind the suggested
connection between double-scaled SYK (DSSYK) and de Sitter space.
We will mention the general form of the correspondence as well as
the mapping of parameters between the two sides. On the...
Abstract: Recently, I have been trying to
understand how large language models (LLMs) work, what their basic
building blocks are and how they are trained. In this talk I want
to share some of my understanding with you by discussing the
so-called...
Abstract: Tidal deformation is a
significant phenomenon observed in various astronomical scenarios,
including black holes, and are a key gravitational-wave observable
encoding information about the object's interior. Relying on hidden
symmetries...
Abstract: I will present the problem of
building local AdS bulk observables from boundary CFT data.
Focusing on QFTs coupled to a rigid AdS background, we study the
analyticity constraints that bulk locality imposes on
bulk-boundary-boundary 3-point...
Abstract: We will review some recent work
with M. Beccaria and S. Giombi on checking AdS/CFT duality by
reproducing certain supersymmetric localization results in 3d
superconformal Chern-Simons-matter (ABJM) theory
by semiclassical quantization...
Abstract: Earlier this year NANOGrav, along
with other pulsar timing arrays, announced strong evidence for a
stochastic gravitational wave (GW) background at nanohertz
frequencies. For decades, such a signal has been predicted
from binaries of...
Abstract: I will discuss a new holographic
duality between a 1d theory, the q-Schwarzian, and certain 2d
dilaton gravity theories. This q-Schwarzian is a one parameter
deformation of the well known Schwarzian theory. For real values of
q, upon...
Abstract: The Bardeen-Cooper-Schrieffer (BCS)
theory of superconductivity described all superconductors until the
1986 discovery of the high-temperature counterpart in the cuprate
ceramic materials. This discovery has challenged conventional
wisdom...
Abstract: In this talk, I will first review the
proposal by Daniel Jafferis and Lampros Lamprou about the
reconstruction of a bulk infalling observer in terms of modular
flow (see 2009.04476), and then apply this proposal to SYK model in
thermofield...
