Inelastic decay rate of quasiparticles in a two-dimensional spin-orbit coupled electron system

Abstract

We present a study of the inelastic decay rate of quasiparticles in a two-dimensional electron gas with spin-orbit interaction. The study is done within the G0W0 approximation. The spin-orbit interaction is taken in the most general form that includes both Rashba and Dresselhaus contributions linear in magnitude of the electron 2D momentum. Spin-orbit interaction effect on the inelastic decay rate is examined at different parameters characterizing the interaction strength in the electron gas.
