Dr Costis Papageorgakis

Profile

I am a Reader in Theoretical Physics at the Centre for Theoretical Physics, Department of Physics and Astronomy. My work has focussed on various aspects of supersymmetric/superconformal field theories and their relation to String/M-theory.

I hold an undergraduate diploma from the University of Patras (Greece), an MSc from Durham University and a PhD from Queen Mary University of London. I have previously held postdoctoral positions at the Tata Institute of Fundamental Research (India), King's College London and Rutgers University (USA). 

Teaching

I teach the MSc/MSci course "Differential Geometry in Theoretical Physics" (DGTP) and the undergraduate course "Quantum Mechanics and Symmetry", over the first and second semesters respectively of the 2023-2024 academic year.

I am a Fellow of Advance HE.

Research

Research Interests:

My current research focuses on the application of modern Machine Learning techniques to a diverse set of problems in theoretical and mathematical physics. 

In the recent past I have investigated various aspects of superconformal field theories in multiple dimensions. A broad toolkit of approaches and techniques can be used to that effect, including the conformal bootstrap, the study of anomalies, superconformal indices and exact methods such as supersymmetric localisation. I have also researched the dynamics of solitons undergoing acceleration.

Older research involved the study of D-brane and M-brane dynamics, in string and M-theory respectively, as well as the structure of their associated supersymmetric/superconformal gauge theories. I have worked towards understanding multiple M2-branes in terms of superconformal Chern-Simons-matter theory in three dimensions, and multiple M5-branes through the superconformal (2,0) theory in six dimensions.

I am also interested in taking on new students for the following project:

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.
