Description:
Author(s): Akihiko Sekine, Dimitrie Culcer, and Allan H. MacDonald The authors present here a general quantum kinetic equation for the Bloch-state density matrix of a crystal that accounts for disorder, and for electric and magnetic fields. The theory naturally incorporates momentum-space Berry phase effects that can have an especially important influence on transport in topological materials. As an illustration, they have considered the steady state of a Weyl semimetal that is driven by parallel electric and magnetic fields, showing explicitly how the chiral magnetotransport anomaly emerges when intervalley scattering is very weak.
