An introduction to geometric phases in quantum materials

The next seminar in the series PH4511: Seminars in Mathematical Physics will be on Monday 23rd March at 10:30am and will be contributed by Associate Professor Justin Song of PAP. This seminar series is targeted at students in Mathematical Physics, but everyone is welcome.

Abstract:

Phenomena sensitive to phase information are particularly prized in materials as they often signal inherently quantum processes: e.g., quantum tunnelling, quantum superconducting flow, and coherent oscillations. In this talk, I will introduce a (relatively) recent phase sensitive principle that is currently at the forefront of materials physics and condensed matter theory: geometric phases. I will discuss how and why they emerge and briefly introduce how they dramatically affect the responses of quantum materials.
