Circularly polarized resonant Rayleigh scattering and Skyrmions in theν = 1 quantum Hall ferromagnet

Abstract

We use the circularly polarized resonant Rayleigh scattering (RRS) to study the quantum Hall ferromagnet at $\ensuremath{\nu}$ $=$ 1. At this filling factor, we observe a right-handed copolarized RRS which probes the Skyrmion spin texture of the electrons in the photoexcited ground states. The resonant scattering is not present in the left-handed copolarization, and this can be related to the correlation between Skymionic effects, screening, and spin wave excitations. These results evidence that RRS is a valid method for the study of the spin texture of the quantum Hall states.
