Transverse dipole spin modes in quantum dots

Abstract

We have carried out a systematic analysis of the transverse dipole spin response of a large size quantum dot within time-dependent current density functional theory. Results for magnetic fields corresponding to integer filling factors are reported, as well as a comparison with the longitudinal dipole spin response. As in the two dimensional electron gas, the spin response at high spin magnetization is dominated by a low energy transverse mode.
