Abstract

We investigate polarization-resolved fine structure in the photoluminescence (PL) in the fractional quantum Hall effect regime at B=4-6 T, where small Zeeman energy allows spin-depolarized ground states. We observe up to five distinct peaks with characteristic polarization and temperature dependence in the vicinity of =1/3 and quenching of the PL from triplet charged quasiexcitons at around =1/4. Those findings appear to be consistent with results of exact diagonalization on a Haldane sphere including all spin configurations and are understood to be PL from fractionally charged quasiexcitons.
