Abstract: We develop a non-perturbative definition of RMT2: a generalization of random matrix theory that is compatible with the symmetries of two-dimensional conformal field theory. Given any random matrix ensemble, its n-point spectral...

Abstract: A recursive extension of $\phi^3$ amplitudes was discovered in 2019 by CEGM.  The first layer is a familiar integral over the positive moduli space $M^+_{0,n}$; the second layer is an integral over the moduli space of polygons in the...

Abstract: We construct the classical phase space of Jackiw-Teitelboim (JT) gravity with positive cosmological constant on spatial slices with circle topology. We identify solutions not previously discussed in the literature, and find the phase space...

Abstract: Historically, the synergy between physics and geometry, from the time of Archimedes and Newton to the era of Einstein, has repeatedly catalyzed breakthroughs in physics and mathematics. In this presentation, we will explore a new narrative...

The identity of dark matter is one of the biggest outstanding questions in astrophysics today. The smallest galaxies in the universe, dwarf galaxies, are powerful probes of its identity, as they are composed predominantly of dark matter.  However...

Abstract: We begin with understanding scalar color-ordered amplitudes via the kinematic mesh and the ABHY associahedron. There are three important aspects of this construction: its zeros, large deformations and splitting. The zeros will imply the...

Abstract: One of the best understood AdS/CFT incarnations relates tensionless k=1 strings on AdS3 to a symmetric product CFT2. I will discuss an exact duality between string theory on a spacetime which is not asymptotically AdS and a non-conformal...

Abstract: We establish local well-posedness for the Einstein-Euler system with a physical vacuum boundary in spherical symmetry. Our proof relies on a new way of thinking about Einstein’s equations in spherical symmetry that is well-adapted to the...

Abstract: Quantum condensed matter has traditionally focused on ground states and equilibrium properties of spatially extended systems, such as electrons in crystalline materials. However, the advent of noisy-intermediate-scale-quantum (NISQ)...

Abstract: Informally, a quantum cellular automaton (QCA) describes some discrete-time local dynamics of a quantum system.  Formally, a QCA is a *-automoprhism of the algebra of local operators.  Local quantum circuits provide one example of QCA, but...
