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…
Orbital Hall effect in spin-3/2 hole-doped semiconductors and its implications for orbitronics
James H. Cullen, Zhanning Wang, Dimitrie Culcer
State-of-the-art magnetic devices rely on faster, more efficient memory elements. A major recent advance is the discovery of orbital torques, which use the orbital angular momentum…
