Inter-band coherence effects in disordered crystals: beyond the non-crossing approximation
Zhanning Wang, James H. Cullen, Roberto Raimondi +1
We develop a quantum kinetic theory for Bloch electrons driven by a uniform dc electric field, extending the nonequilibrium density-matrix formalism beyond the non-crossing approxi…

Quantum geometry and dipolar dynamics in the orbital magneto-electric effect
James H. Cullen, Daniel P. Arovas, Roberto Raimondi +1
We show that the orbital magneto-electric effect (OME) -- the generation of a steady-state orbital angular momentum density -- is partly the result of a nonequilibrium dipole momen…
