Berry phase in the phase space worldline representation: The axial anomaly and classical kinetic theory

P Copinger, S Pu - Physical Review D, 2022 - APS
The Berry phase is analyzed for Weyl and Dirac fermions in a phase space representation of
the worldline formalism. Kinetic theories are constructed for both at a classical level …
