Spin current generation by helical states in a quasi-one-dimensional system
Manuel Valin-Rodriguez
Time-reversal symmetry and rotational invariance in spin space characterize usual non-magnetic conductors. These symmetries give rise, at least, to four-fold degenerate multiplets…
Predicted signatures of the intrinsic spin Hall effect in closed systems
Manuel Valin-Rodriguez
We study a two-dimensional electron system in the presence of spin-orbit interaction. It is shown analytically that the spin-orbit interaction acts as a transversal effective elect…
Spin control in semiconductor quantum wires
R. G. Nazmitdinov, K. N. Pichugin, M. Valin-Rodriguez
We show that spin-flip rotation in a semiconductor quantum wire, caused by the Rashba and the Dresselhaus interactions (both of arbitrary strengths), can be suppressed by dint of a…
Interplay between Zeeman interaction and spin-orbit coupling in a two-dimensional semiconductor system
Manuel Valin-Rodriguez, Rashid G. Nazmitdinov
We analyse the interplay between Dresselhaus, Bychkov-Rashba, and Zeeman interactions in a two-dimensional semiconductor quantum system under the action of a magnetic field. When a…
Intrinsic spin dynamics in semiconductor quantum dots
Manuel Valin-Rodriguez
We investigate the characteristic spin dynamics corresponding to semiconductor quantum dots within the multiband envelope function approximation (EFA). By numerically solving an $8…
Renormalization of spin-orbit coupling in quantum dots due to Zeeman interaction
Manuel Valin-Rodriguez
We derive analitycally a partial diagonalization of the Hamiltonian representing a quantum dot including spin-orbit interaction and Zeeman energy on an equal footing. It is shown t…
