Formal derivation of quantum drift-diffusion equations with spin-orbit interaction
Luigi Barletti, Philipp Holzinger, Ansgar Jüngel
Quantum drift-diffusion equations for a two-dimensional electron gas with spin-orbit interactions of Rashba type are formally derived from a collisional Wigner equation. The collis…

Wigner function with correlation damping
l. Barletti, P. Bordone, L. Demeio +1
We examine the effect of the decoherence-induced reduction of correlation length on a one-dimensional scattering problem by solving numerically the evolution equation for the Wigne…
