Zitterbewegung velocity in semiclassical electron dynamics
Dimitrie Culcer
Zitterbewegung plays a major role in electron dynamics in solids, yet is not captured in conventional semiclassical treatments. Here, starting from the quantum Liouville equation,…
Current-induced spin torques in III-V ferromagnetic semiconductors
Dimitrie Culcer, M. E. Lucassen, R. A. Duine +1
We formulate a theory of current-induced spin torques in inhomogeneous III-V ferromagnetic semiconductors. The carrier spin-3/2 and large spin-orbit interaction, leading to spin no…
Spin precession and alternating spin polarization in spin-3/2 hole systems
Dimitrie Culcer, C. Lechner, R. Winkler
The spin density matrix for spin-3/2 hole systems can be decomposed into a sequence of multipoles which has important higher-order contributions beyond the ones known for electron…
Coherent wave-packet evolution in coupled bands
Dimitrie Culcer, Yugui Yao, Qian Niu
We develop a formalism for treating coherent wave-packet dynamics of charge and spin carriers in degenerate and nearly degenerate bands. We consider the two-band case carefully in…
