Abstract: Topological defect lines in 2D CFTs have found resurgence in the context of categorical symmetries. In this talk, I will present the lattice realization of these for unitary Minimal Models. I will use Spin chains, such as Transverse Field...

Abstract: An underappreciated aspect of quantum mechanics is that large, relatively imperfect systems can show behavior that is as precise and reproducible as anything in nature. The first example was the observation of superconductivity in 1911...

Abstract: The method of exhaustively-symmetrized light-cone quantization (eLCQ) is described. As a continuous approach to solving quantum bound-state problems, it exploits the symmetries of physical systems to generate an optimal set of basis...

Abstract: I will discuss the log(N) corrections to the Euclidean gravitational path integral in the context of the AdS/CFT correspondence for 3d SCFTs arising from N M2-branes. These corrections can be computed in 4d gravity using heat kernel...

Abstract: Many BSM models predict new long-lived particles that could be produced at the LHC and travel measurable distances before decaying. This talk will focus on a set of low-background searches for long-lived particles using the LHC Run 2...

Abstract: Meromorphic amplitudes are the simplest non-trivial scattering amplitudes. They describe the exchange of infinitely many higher spin resonances in theories like string theory and large N gauge theories. Yet, despite being very simple...

Abstract: Many recent developments in matrix models and topological string theory have been driven by resurgence methods. 

I will introduce basic resurgence concepts in the context of hermitian matrix models (and their double scaling limits) and...

Abstract: I will describe constructions of lattice field theories that assign a single bosonic variable to each site, rather a conjugate pair x,p. The information to realize a non-trivial dynamics is realized by non-trivial Poisson brackets between...

Abstract: I will discuss work in progress with M. Disconzi on spherically symmetric solutions to the Einstein– Euler equations. The main result is local well-posedness for a class of initial data satisfying the physical vacuum condition. This is the...

Abstract: I will summarize recent results on the large N limit of path integrals of 3d SCFTs arising on the worldvolume of N M2-branes placed on compact Euclidean manifolds. The leading N^3/2 term in the large N expansion of these "free energies"...
