Dr Matt Hodgson

Associate Lecturer of Theoretical Physics

   

About

I am an Associate Lecturer of Theoretical Physics at the University of York, UK with over ten years of research experience in many-body quantum theory. I completed my PhD under Prof. Rex Godby at the University of York in 2016. From 2016 to 2019, I was a postdoc with Prof. Hardy Gross at the Max Planck Institute of Microstructure Physics in Germany. I then worked as a researcher at Durham University before becoming an Associate Lecturer in 2021.

Research

My research focuses on the fundamentals of quantum theory and its application to modelling the electron excitation properties of materials. My research contributions include the authorship of the iDEA code, a comprehensive Python software library for exploring and understanding many‑body quantum mechanics, fundamental insights into the calculation of excited electron states within density functional theory, and the development of a method for accurately simulating many‑electron real‑time dynamics.

Electron excitation

Kohn and Sham's approach to density functional theory is the most popular method in materials science; however, it is notoriously unreliable for calculating electron excitation properties.

Electron dynamics

Modelling the response of electrons to an applied electric field remains a challenge; yet determining the flow of charge through a material is crucial for the design of integrated circuits.

Electron emission

Many-body perturbation theory is commonly used to calculate the spectral function; however, increasing the accuracy of this approach is challenging owing to the computational cost.
