Research paperTheoreticalElectronic Raman scattering from 2D metals with broken inversion symmetryMojdeh Saleh, Saurabh MaitiarXiv·2026·10.1063/1.1748067·arXiv:2604.00486AbstractWe formulate a theory of inelastic light scattering from charge carriers in metals lacking inversion symmetry, showing that breaking SU(2) symmetry through spin-orbit coupling enables electronic Raman scattering to couple directly to spin excitations without resonant tuning. We analyze doped or gated graphene on substrates with Rashba and valley-Zeeman spin-orbit coupling and compare the resulting spectra with a model two-dimensional electron gas, identifying strong polarization-dependent resonances and step features sensitive to the spin structure of the low-energy Hilbert space.Read more
