Spin and density response of interacting particles with spin-orbit coupling — •Klaus Morawetz1,2, Janik Kailasvuori3, and Ozgur Bozat2 — 1University of Applied Science Münster, Stegerwaldstrasse 39, 48565 Steinfurt, Germany — 2International Institute of Physics (IIP), Universidade Federal do Rio grande do Norte - UFRN, Brazil — 3Max-Planck-Institute for the Physics of Complex Systems, Noethnitzer Str. 38, 01187 Dresden, Germany
Linearizing the appropriate kinetic equation, the density and spin response functions of an interacting particle system coupled to an external magnetic field is derived. Special attention is paid to the spin-orbit coupling. Different known cases are contained in the obtained expression, among them magnetized plasmas in high magnetic fields, quasi two-dimensional graphene with interband coupling and spin-polarized electrons interacting with impurities. The interplay between collective spin and charge phenomena dependent on the interaction and the magnetic field is presented and the resulting transport coefficients are calculated.
