### The Euclidean Path Integral in Supergravity

I will review some interesting features regarding the spectrum of near-extremal black holes in gravity and near-BPS black holes in supergravity, which are derived from the Euclidean path integral. For simplicity, I will focus on the case of charged...

### The p-spin Glass Model: A Holographer's Perspective

I will discuss a large-N bosonic quantum mechanical sigma-model with a spherical target space subject to disordered interactions, more colloquially known as the p-spin spherical model. Replica symmetry is broken at low temperatures and for...

### Naturalness and muon anomalous magnetic moment

Based on https://arxiv.org/abs/2106.01373. We study a model for explaining the apparent deviation of the muon anomalous magnetic moment, (g-2), from the Standard Model expectation. There are no new scalars and hence no new hierarchy puzzles beyond...

### Quantum Computing and the Difficulty of Simulating Quantum Many-Body Systems

Ignacio Cirac

Quantum many-body systems are very hard to simulate, since computational resources (time and memory) typically grow exponentially with the system size. However, quantum computers or analog quantum simulators may perform that task in a much more...

### Superstring Amplitudes in Genus 0 and Double Copy

This is joint work with Clément Dupont. Motivated by double-copy  (Kawai-Lewellen-Tye) formulae relating open and closed superstring amplitudes at tree-level, I will explain a general double-copy formula for period integrals on algebraic varieties...

### Conformal Colliders Meet the LHC

Ian Moult

Lightray operators have played an important role in numerous recent developments in conformal field theory. These operators, and their associated operator product expansion (OPE), also play a central role in collider experiments, where they govern...

We revisit the computation of string correlation functions in AdS3 with pure NS-NS flux from a worldsheet point of view. These correlators contain all the perturbative information about the spacetime CFT and the existence of winding strings in AdS3...

### Khovanov Homology from Mirror Symmetry

Mina Aganagic

Khovanov showed, more than 20 years ago, that there is a deeper theory underlying the Jones polynomial. Theknot categorification problem” is to find a uniform description of this theory, for all gauge groups, which originates from physics. I found...

### Spontaneously Broken Boosts in CFTs

Conformal Field Theories (CFTs) have rich dynamics in heavy states. We describe the constraints due to spontaneously broken boost and dilatation symmetries in such states. The spontaneously broken boost symmetries require the existence of new low...

### Some Half-Baked Thoughts about de Sitter Space

The question I will address is: How does the holographic principle apply to de Sitter space?
