# Theoretical Physics

The Theoretical Physics group’s interest lies in advancing our understanding of fundamental physics phenomena, and using this knowledge to predict and describe new experiments and applications.

Our research ranges from classical wave theory to quantum information theory, to condensed matter physics and nano physics. For example, we investigate the electromechanical properties of nanoscale materials such as graphene, the spin dynamics of magnetic materials at ultrafast timescales, the light-matter interactions between light and metamaterials, and the occurrence of Hawking radiation in laboratory systems.

To tackle these topics we use analytical and numerical methods including classical wave theory, quantum optics, density functional theory (DFT), micromagnetics and magnonics, and exactly solvable models.
