Semiclassical theory of weak antilocalization and spin relaxation in ballistic quantum dots
Semiclassical theory of weak antilocalization and spin relaxation in ballistic quantum dots
We develop a semiclassical theory for spin-dependent quantum transport in ballistic quantum dots. The theory is based on the semiclassical Landauer formula, that we generalize to include spin-orbit and Zeeman interaction. Within this approach, the orbital degrees of freedom are treated semiclassically, while the spin dynamics is computed quantum mechanically. …
