Effect of the spin–orbit coupling on the Raman spectra of a GaAs quantum ring with few electrons

The resonant inelastic light scattering from a GaAs quantum ring containing a few electrons is investigated theoretically in the presence of Rashba spin–orbit coupling. The spin–orbit interaction generates additional Raman transitions in the ring, whose amplitudes can be controlled externally by varying the spin–orbit coupling parameter. We also find that with an increase of the external magnetic field, there is a remarkable change in the Raman spectrum of a quantum ring due to the Aharonov–Bohm oscillations.
