Type IIB supergravity famously has a discrete duality group, which is an exact symmetry of the full type IIB string theory. This symmetry has potential quantum anomalies, which could render the theory inconsistent. In this talk I will describe how...

We construct vacua of string theory in which all moduli are stabilized and the magnitude of the cosmological constant is exponentially small.  The vacua are supersymmetric AdS_4 solutions in flux compactifications of type IIB string theory on...

The operator product expansion of massless celestial primary operators of arbitrary spin is investigated.  Poincare symmetry is found to imply a set of recursion relations on the operator product expansion coefficients of the leading singular terms...

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...

 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...

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 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...

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...

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...
