Title: How to Compute Using Quantum Walks Abstract: Quantum walks are widely and successfully used to model diverse physical processes. This leads to computation of the models, to explore their properties. Quantum walks have also been shown to… Read More

Title: Resurgence, Phase Transitions & Extrapolation Abstract: There are several important conceptual and computational questions in quantum field theory which have recently been approached from a new perspective motivated by “resurgent asymptotics”, which is a novel mathematical formalism that… Read More

Title: Black Holes and How They Might Be Sources of New Physics Abstract: Particle theorists using string theory have ideas about black holes but encountered various problems and contradictions. However, considering standard physics and some straightforward extrapolations leads to a clearer picture. Black holes seem to tell us not only important things about particle… Read More

Title: Bootstrapping Matrix Quantum Mechanics Abstract: Matrix quantum mechanics theories are at the heart of holography, but only the simple case of a single matrix has been tractable. We have developed a new method to calculate the spectrum and expectation values of… Read More

Title: Chiral Boundary States for Fermions Abstract: I’ll describe boundary conditions for fermions in d=1+1 dimensions, using the framework of boundary conformal field theory. I’ll explain how boundary states are classified by a mod 2 index, related to their SPT phase, describe… Read More

Title: Buildings, Quaternions and Yang-Baxter Equations Abstract: To be useful in theoretical physics, mathematical structure  has to be sufficiently rich and cover several fields of mathematics, physics and, potentially, computer science. One of the barriers to overcome is different… Read More
