Geometric Correlations and Breakdown of Mesoscopic Universality in Spin Transport
Geometric Correlations and Breakdown of Mesoscopic Universality in Spin Transport
We construct a unified semiclassical theory of charge and spin transport in chaotic ballistic and disordered diffusive mesoscopic systems with spin-orbit interaction. Neglecting dynamic effects of spin-orbit interaction, we reproduce the random matrix theory results that the spin conductance fluctuates universally around zero average. Incorporating these effects into the theory, …
