Title: From Ramanujan to Rokhlin, via Quantum States Abstract: The goal of the talk, intended for a broader audience, will be tointroduce a class of functions that originate from physics, answer aquestion in topology, can be computed via methods more common in the theoryof dynamical systems, and in the end turn out to enjoy beautiful modularproperties of the type first observed by Ramanujan.

Title: Accelerating Black Hole Chemistry Abstract: One of the more curious exact solutions of Einstein gravity is the“C-metric”, a metric representing an accelerating black hole, the forcebeing provided by a cosmic string emerging from the black hole horizon. Theblack hole is neither isolated, nor static, unless we embed it in AdS anddrop the acceleration below the AdS scale – a so called “slowly acceleratingblack hole”. I will describe how to derive thermodynamics for thenon-isolated black hole, including the cosmic string tension as athermodynamical variable — as a result, a new chemical potential isintroduced, the thermodynamic length. I will also discuss a set of extensivevariables, or chemical expressions for the black hole that do not involveany reference to the geometrical parameters and describe some criticalphenomena for the black hole.

Title: Integrability, Rationality & Convolutions Abstract: The Eisenstein-Kronecker function is a useful object in number theory and physics. It is a tool for proving rationality for period integrals of cusp forms. It generates integration kernels of elliptic polylogarithms… Read More

Title: Universal Fault Tolerant Quantum Computing with 3D Surface Codes Abstract: Quantum computing hardware is making impressive advances but the construction of a large scale fault tolerant quantum computer remains a significant challenge. Part of this difficulty is… Read More

Title: Quiver Yangian from Crystal Melting Abstract: The BPS counting of type IIA string theory on non-compact toric Calabi-Yauthreefolds can be described by crystal melting. I will explain how to construct the BPS algebras for these theories by a “bootstrap” method, whereone solves for the algebra by demanding that it acts on the correspondingBPS crystal appropriately. The resulting algebras are quiver Yangians Y(Q,W)that are associated with the quiver and the superpotential of the theory.Based on joint work with M. Yamazaki (arxiv: 2003.08909).

Title: An Exact AdS/CFT Duality Abstract: The AdS/CFT correspondence relates string theory on an Anti de Sitter (AdS) background to a dual conformal field theory (CFT) living on the boundary of AdS. One promising strategy for how to prove the duality… Read More
