Random spin-orbit coupling and spin relaxation in symmetric quantum wells
The effective “spin–orbit” field acting upon spins of carriers in two-dimensional electronic structures (the Rashba field) arises due to the spatial asymmetry of the system. It will be shown in this
Probing variations of the Rashba spin-orbit coupling at the nanometre scale
Scanning tunnelling spectroscopy provides access to the spatial variations in the strength of Rashba spin–orbit coupling in a two-dimensional electron system, with local fluctuations shown to cause
Spin dephasing and pumping in graphene due to random spin-orbit interaction
We consider spin effects related to the random spin-orbit interaction in graphene. Such a random interaction can result from the presence of ripples and/or other inhomogeneities at the graphene
Fast and robust spin manipulation in a quantum dot by electric fields.
An invariant-based inverse engineering method is applied to control, by time-dependent electric fields, the spin dynamics in a quantum dot with spin-orbit coupling in a weak magnetic field, which can open new possibilities for spin-based quantum information processing.
Spin relaxation in quantum dots with random spin-orbit coupling
We investigate the longitudinal spin relaxation arising due to spin-flip transitions accompanied by phonon emission in quantum dots where the strength of the Rashba spin-orbit coupling is a random
Spin dynamics in a strongly driven system: Very slow Rabi oscillations
We consider joint effects of tunneling and spin-orbit coupling on driven by electric field spin dynamics in a double quantum dot with a multi-level resonance scenario. We demonstrate that tunneling
Raman scattering in YBa 2 Cu 3 O 7 : A comprehensive theoretical study in comparison with experiments
All Raman-active phonon modes of YBa 2 Cu 3 O 7 are investigated by first-principles linearized augmented plane-wave calculations based on density-functional theory for a fully optimized crystal
Effect of gate-driven spin resonance on the conductance through a one-dimensional quantum wire
We consider quasiballistic electron transmission in a one-dimensional quantum wire subject to both time-independent and periodic potentials of a finger gate that results in a coordinate- and
Minimum of spin-orbit coupling in two-dimensional structures
Spin-orbit coupling in symmetrically doped Si/Si 1 - x Ge x quantum wells is investigated theoretically. Unavoidable fluctuations of concentration of dopant ions lead to a finite spin-orbit coupling
