We study the Lyapunov exponent in disordered quantum field theories. Generically the Lyapunov exponent can only be computed in isolated CFTs, and little is known about the way in which chaos grows as we deform the theory away from weak coupling. In...

In this talk, we explore new techniques to probe the analytic structure of scattering amplitudes in perturbative Quantum Field Theory. The goal of this approach is to leverage symmetries, limits, and analyticity in order to circumvent the explicit...

Quantum computers employ quantum circuits to implement algorithms. They are composed of quantum gates that act on near neighbors according to some spatial geometry. They are particular instances of quantum cellular automata (QCA), the set of...

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...
