PGI-1 Talk: Prof. Dr. Qian Niu

Quantum Theory of Materials Seminar

Particle view in crystals

He will present a particle view of electrons in crystals based on semiclassical dynamics and describe how Berry curvatures modify thermodynamic and transport properties. He will then discuss more recent work on deformed crystals using a geodynamic language, and obtain Hall viscosity, flexsoelectric and flexsomagnetic responses. When the results are extended to 4d spacetime crystals, the geodynamics becomes greatly simplified and unified, allowing a fresh look of table-top general relativity. The talk may resonate with the general physics audience.
