A quantum graph approach to metamaterial design

Hello, everyone. I am pleased to introduce Professor Gregor Tanner from the University of Nottingham. Professor Tanner specializes in wave asymptotics, quantum chaos, and metamaterials design using quantum graph theories. He will present on the Quantum Graph Approach to Metamaterials Design.

Thank you, Bogdan, for organizing this event, and I appreciate Bryn's invitation, despite his absence today. The concept I will discuss originated a couple of years ago while we were exploring quantum graphs as a means to understand various properties of quantum systems and their connection to quantum chaos. This led us to consider whether we could apply this framework to study metamaterials, which are typically regular and periodic but possess unique characteristics at certain nodes.

Tristan Lawrie further developed this idea during his PhD, and much of my presentation today will focus on his contributions, which include numerous innovative concepts. This research began in collaboration with Dimitris Chronopoulos, who is currently at KU Leuven. Additionally, we have established a strong partnership with Gregory Chaplin and his team at the University of Exeter, and I will share some of their experimental findings later in the presentation.

Here, you can see several publications that resulted from this work, highlighting Tristan's significant contributions. He is currently a postdoctoral researcher at both Exeter and Nottingham.
