53. Large N Partition Functions, Holography, and Black Holes

Nikolay Bobev

04/07/2023 14:00

I will discuss the large N behavior of partition functions of
the ABJM theory on compact Euclidean manifolds. I will pay particular
attention to the S^3 free energy and the topologically twisted index for
which I will present closed form expressions valid to all orders in the
large N expansion. These results have important implications for
holography and the microscopic entropy counting...

54. Revisiting logarithmic corrections to supersymmetric black hole entropy

Ashoke Sen

05/07/2023 11:00

In this talk we shall review the old and new approaches to computing logarithmic correction to supersymmetric black hole entropy.

50. Information Recovery from Black Holes via Islands

Prem Kumar

05/07/2023 15:45

I will review ingredients of the island mechanism for evaluating entropies of entanglement of Hawking radiation from black holes. I will then focus on the problem of information recovery, for an object carrying energy and entropy thrown into a black hole, using the generalized entropy formalism within the framework of JT gravity, where the backreaction problem can be solved.

55. Large Charge 't Hooft Limit of N=4 Super-Yang-Mills

Shota Komatsu

The planar integrability of N = 4 super-Yang-Mills (SYM) is the cornerstone for numerous exact observables. We show that the large charge sector of the SU(2) N = 4 SYM provides another interesting solvable corner which exhibits striking similarities despite being far from the planar limit.

56. Going beyond the spectrum in planar N=4 SYM with integrability and crossing symmetry

Nikolay Gromov

06/07/2023 14:00

We continue to develop a method merging Integrability and Conformal Bootstrap to extract CFT data in integrable conformal gauge theories such as N =4 SYM.
We consider the 1D defect CFT defined line in the theory, whose non-perturbative spectrum is governed by the Quantum Spectral Curve (QSC). In addition, we use that the deformed setup of a cusped Wilson line is also controlled by the QSC,...

57. The (classical) theory of fields

Diego Hofman

07/07/2023 11:00

A new look at electromagnetism and gravity.

58. Defects in QFT above 2 Dimensions

Zohar Komargodski

07/07/2023 13:45

We review recent ideas about defects in QFT, including general theorems and examples of defects in magnets and gauge theories.
