Quantum kinetic theory in curved spacetime
byKazuya Mameda
Abstract:In this talk, I will explain my recent works about the kinetic theory under external gravity. I will first show its field-theoretical derivation keeping the general covariance. From this framework, we obtain new types of fermionic transport phenomena induced by gravity; in particular, the coupling between spin and Riemann curvature yields the antiparallel flows of charge and energy. These phenomena are applicable not only to fermionic systems under genuine gravity, but also to the ones with background fluid motion or temperature gradient. I will briefly discuss possible applications to high-energy and condensed matter physics. I will also talk about photonic kinetic theory in curved spacetime and its implication.
Keywords:
kinetic theory, general relativity.
