Abstract: We introduce an effective field
theory (EFT) for conformal impurities, constructed from pairs of
transversely displaced defects. This EFT captures the universal
signature of an impurity on heavy local operators. In the case of
conformal...
Abstract: We present a wholly self-consistent,
complete cyclic bouncing cosmology based on components drawn from
string theory and constructed in a way that is under perturbative
control throughout (e.g., with temperatures well below the
string...
Abstract: On September 14th 2015, the LIGO
detectors opened a new window onto the universe with the first
direct detection of gravitational waves from a binary black hole
merger. This first event alone had profound implications for tests
of general...
Abstract: Black hole perturbation theory
captures a few important effects in the dynamics of binary mergers,
such as tidal deformations and the decay of ringdown modes. It also
describes the physics of the photon ring. However,
extracting...
Abstract: This will be the first amplitudes
meeting of the year. There is no scheduled talk; instead, we will
use this session to outline topics of interest for the group and to
discuss recent papers.
Abstract: Thermal correlators in large N
systems equilibrate at late times, but the precise
functional behavior is unknown away from holographic and free field
limits. In this talk I will analyze this problem in the case of the
SYK model at high...
