The Magnetic Field

The many body interaction are investigated in polarization resolved photoluminescence in the magnetic field up to 23 T. The Fermi edge singularity, Anderson-Fano transition and neutral and negatively charged excitons (trions) are detected in the photoluminescence spectra. The experimental results are supplemented by realistic calculations.
