Electric-field driven long-lived spin excitations on a cylindrical surface with spin-orbit interaction
P. Kleinert
Based on quantum-kinetic equations, coupled spin-charge drift-diffusion equations are derived for a two-dimensional electron gas on a cylindrical surface. Besides the Rashba and Dr…
Superconductivity from four Fermion complexes
P. Kleinert
Superconductivity is studied for a fermionic system with attractive four-body interaction. Applying a Green function approach, the gap equation is derived. From the solution, the t…
Field-induced spin excitations in Rashba-Dresselhaus two-dimensional electron systems probed by surface acoustic waves
P. Kleinert, V. V. Bryksin
A spin-rotation symmetry in spin-orbit coupled two-dimensional electron systems gives rise to a long-lived spin excitation that is robust against short-range impurity scattering. T…
Coupled spin-charge drift-diffusion equations for the Rashba model
V. V. Bryksin, P. Kleinert
Coupled spin-charge drift-diffusion equations are derived for a biased two-dimensional electron gas with weak Rashba spin-orbit interaction. The basic equations formally agree with…
