High Energy Theory Seminar

The Holographic Dual of Strongly γ-deformed N=4 SYM Theory
2:30pm|Bloomberg Lecture Hall
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...

Globally Consistent Three-family Standard Models in F-theory
2:30pm|Bloomberg Lecture Hall
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...

Quantum Epidemiology: Operator Growth, Thermal Effects, and SYK
2:30pm|Bloomberg Lecture Hall
In many-body chaotic systems, the size of an operator generically grows in Heisenberg evolution, and is measured by out-of-time-ordered four-point functions. However, these only provide a coarse probe of the full underlying operator growth structure...

The Kreuzer-Skarke Axiverse
Liam McAllister
2:30pm|Bloomberg Lecture Hall
I will describe a large ensemble of compactifications of type IIB string theory on Calabi-Yau threefold hypersurfaces, obtained by triangulating polytopes from the Kreuzer-Skarke list. We have developed methods to compute effective theories in the...

The Fuzzball Paradigm for Black Holes and Its Possible Implications for Cosmology
Samir Mathur
2:30pm|Bloomberg Lecture Hall
In 1975 Hawking showed that the evaporation of black holes creates a problem for unitarity. This argument can be made rigorous through the small corrections theorem, and implies that there must be a fundamental change in our picture of semiclassical...

Twisted holography for the N=4 chiral algebra
Kevin Costello
2:30pm|Bloomberg Lecture Hall
Beem et al. used a superconformal supercharge to localize N=4 Yang-Mills to a two-dimensional chiral theory. I will discuss my work with Gaiotto, in which we analyze the holographic dual of this localization. We argue that the same localization...

Under Construction: A Progress Report on a Theory of SUSY Representations
S. James Gates, Jr.
2:30pm|Bloomberg Lecture Hall
Compact Lie Algebras su(N) have aspects of their representations conveniently expressed in terms of matrices, but they also have some aspect that are most conveniently described by terms of graphical means, i.e. weight spaces, root space, Dynkin...

’t Hooft Anomalies, High-T, and Low-T Domain Walls in Adjoint Fermion Theories with (or without) Supersymmetry
Erich Poppitz
2:30pm|Bloomberg Lecture Hall
We study ’’t Hooft anomalies of 1-form and 0-form symmetries in SU(N) gauge theories with adjoint fermions, focusing on the rich worldvolume physics of domain walls mandated by anomaly inflow. In two semiclassical regimes—one of the high-T theory...
