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…
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…
Zeeman energy and anomalous spin splitting in lateral GaAs quantum dots
Manuel Valin-Rodriguez, Antonio Puente, Llorens Serra
The level splittings induced by a horizontal magnetic field in a parabolic two-dimensional quantum dot with spin-orbit interaction are obtained. Characteristic features induced by…
Quantum dots based on spin properties of semiconductor heterostructures
M. Valin-Rodriguez, A. Puente, L. Serra
The possibility of a novel type of semiconductor quantum dots obtained by spatially modulating the spin-orbit coupling intensity in III-V heterostructures is discussed. Using the e…
Spin splitting and precession in quantum dots with spin-orbit coupling: the role of spatial deformation
Manuel Valin-Rodriguez, Antonio Puente, Llorens Serra
Extending a previous work on spin precession in GaAs/AlGaAs quantum dots with spin-orbit coupling, we study the role of deformation in the external confinement. Small elliptical de…
