This talk will give a brief overview focused on six papers written
by D. Gaiotto, G. Moore, and A. Neitzke
loosely centered around the topics mentioned in the title. The
papers are on the arXiv.
Background reading: Some short reviews are: https:/...
We present a first-principles derivation of a weak-strong duality
between the four-dimensional fishnet theory in the planar limit and
a discretized string-like model living in AdS5. At strong coupling,
the dual description becomes classical and we...
We will introduce ourselves and give a 2 minute description of what
we are interested in at the moment.
The plan for future group meetings is to have some review talks, or
topics for discussions. So please think about suggestions for
things you...
I will discuss recent work that studies the evolution of the von
Neumann entropy of a holographic boundary system dual to an
evaporating black hole in AdS. This entropy is computed via the
Engelhardt-Wall prescription of extremizing the generalized...
We consider supersymmetric $AdS_3\times Y_7$ solutions of type IIB
supergravity dual to N=(0,2) SCFTs in d=2, as well as $AdS_2\times
Y_9$ solutions of D=11 supergravity dual to N=2 supersymmetric
quantum mechanics, some of which arise as the near...
Our Universe is filled with Cosmic Microwave Background (CMB)
radiation having an almost perfect black body spectrum with a
temperature of To=2.7K. The number density of photons in our
Universe exceeds the number density of electrons by a factor of...
Critical points of classical second-order phase transitions are
thermodynamic phenomena of particular interest, driven by thermal
fluctuations and characterized by emergent scale invariance and
universal power-law correlations. At zero temperature...
We present recent advances in constructions of globally
consistent
F-theory compactifications with the exact chiral spectrum of the
minimal
supersymmetric Standard Model. We highlight the first such example
and
then turn to a subsequent systematic...
Anomalies are invariants under renormalization group flow which
lead to powerful constraints on the phases of quantum field
theories. I will explain how these ideas can be generalized to
families of theories labelled by coupling constants like the...
The LIGO/VIRGO collaboration has just started their observing run
3. I will first give an introduction to gravitational wave searches
and the events that have been found so far and describe some of the
interesting astrophysics problems that might be...
