Abstract
The resonance photoluminescence of excited Laughlin liquid at the electron filling factor of 1/3 is studied. It is shown that for a neutral defect in Laughlin liquid consisting of an electron at the upper spin sublevel of the zero Landau level and a valence hole, the influence of random potential fluctuations on the probability of optical recombination of the defect is suppressed (random potential superscreening). Filling the Laughlin liquid with single-spin excitations (spin-magnetogravitons) does not affect this observation.
