Abstract: We derive the theoretical and numerical framework for investigating nonequilibrium properties of spin-orbit coupled wires with Zeeman splitting proximized by a superconductor in the non-linear diffusive regime. We demonstrate that the anisotropic behaviour of triplet… read more here.

DOI: 10.1103/physrevd.103.056025
Abstract: In this work, we study the relativistic quantum kinetic equations in $2+1$ dimensions from Wigner function formalism by carrying out a systematic semiclassical expansion up to $\ensuremath{\hbar}$ order. The derived equations allow us to explore… read more here.

DOI: 10.1103/physrevd.98.081701
Abstract: A modified quantum kinetic equation which takes account of the noninertial features of rotating frame is proposed. The vector and axial-vector field components of the Wigner function for chiral fluids are worked out in a… read more here.
