Abstract <p>The resonant photoluminescence of an excited Laughlin liquid at an electron filling factor of 1/3 was studied. It was shown that, for a neutral defect in a Laughlin liquid that consists 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.</p>
