Abstract

We report an anomalous dispersion of charged excitons in photoluminescence experiments on a two-dimensional electron gas subjected to a quantizing magnetic field around Image . We have found that the anomaly exists only at a very low temperature (0.1 K) and an intermediate electron density (0.9×1011 cm−2). It is explained to occur due to the perturbation of the incompressible liquid at Image . ...
