- Title
Collective Spin Modes in Fermi Liquids with Spin–Orbit Coupling.
- Authors

- Abstract
A combination of spin–orbit coupling and electron–electron interaction gives rise to a new type of collective spin modes, which correspond to oscillations of magnetization even in the absence of the external magnetic field. We review recent progress in theoretical understanding and experimental observation of such modes, focusing on three examples of real-life systems: a two-dimensional electron gas with Rashba and/or Dresselhaus spin–orbit coupling, graphene with proximity-induced spin–orbit coupling, and the Dirac state on the surface of a three-dimensional topological insulator. This paper is dedicated to the 95th birthday of Professor Emmanuel I. Rashba.
