We use the circularly polarized resonant Rayleigh scattering (RRS) to study the quantum Hall ferromagnet at ν = 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.

Abstract
We use the circularly polarized resonant Rayleigh scattering (RRS) to study the quantum Hall ferromagnet at ν = 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.File in questo prodotto:
