Abstract
We present a microscopic theory of Raman scattering in a two-dimensional Fermi liquid (FL) with Rashba and Dresselhaus types of spin-orbit coupling and subject to an in-plane magnetic field . In the long-wavelength limit, the Raman spectrum probes the collective modes of such a FL: the chiral spin waves. The characteristic features of these modes are a linear-in- term in the dispersion and the dependence of the mode frequency on the directions of both and . All of these features have been observed in recent Raman experiments on quantum wells.
