Sidney Baines (jointly with Dr Ulla Blumenschein-PhD expected 2025) Enrico Andriolo (PhD 2023) Gergely Kántor (PhD 2022) Joseph Hayling (PhD 2019) I am also interested in taking on new students for the following project: Project Title Conformal Field Theories and Artificial Intelligence Conformal Field Theories are mathematical descriptions of natural phenomena that look the same at all length scales. They find fundamental applications over a large spectrum of topics ranging from condensed-matter physics, particle physics, string theory and quantum gravity. They are, however, incredibly hard to solve with the exception of a handful of examples. This project aims to exploit the tremendous recent progress in Artificial Intelligence to solve arbitrary conformal field theories. This will be achieved by utilising machine-learning techniques similar to those used by Google’s DeepMind Technologies when building the AlphaGo programme, which spectacularly beat professional Go champions. Requirements: A very good grasp of graduate Quantum Field Theory and supersymmetry, as well as some basic conformal field theory and string theory. Coding experience is desirable.
