Driving spin and charge in quantum wells by surface acoustic waves
Johannes Wanner, Cosimo Gorini, Peter Schwab +1
Recent experiments have shown the potential of surface acoustic waves as a mean for transporting charge and spin in quantum wells. In particular, they have proven highly effective…
Exact time-dependent density functional theory for impurity models
Peter Schmitteckert, Michael Dzierzawa, Peter Schwab
We employ the density matrix renormalization group to construct the exact time-dependent exchange correlation potential for an impurity model with an applied transport voltage. Eve…
Spin-orbit interaction in a two-dimensional electron gas: a SU(2) formulation
R. Raimondi, P. Schwab, C. Gorini +1
Spin-orbit interaction is usefully classified as extrinsic or intrinsic depending on its origin: the potential due to random impurities (extrinsic), or the crystalline potential as…
Inverse Spin Hall Effect and Anomalous Hall Effect in a Two-Dimensional Electron Gas
P. Schwab, R. Raimondi, C. Gorini
We study the coupled dynamics of spin and charge currents in a two-dimensional electron gas in the transport diffusive regime. For systems with inversion symmetry there are establi…
Interplay of intrinsic and extrinsic mechanisms to the spin Hall effect in a two-dimensional electron gas
Roberto Raimondi, Peter Schwab
In order to describe correctly the interplay of extrinsic and intrinsic spin-orbit mechanisms to the spin Hall effect, it is necessary to consider different sources of spin relaxat…
Tuning the Spin Hall Effect in a Two-Dimensional Electron Gas
R. Raimondi, P. Schwab
We provide a theoretical framework for the electric field control of the electron spin in systems with diffusive electron motion. The approach is valid in the experimentally import…
