Incompressible electron liquid states studied by optical spectroscopy.
Luminescence spectroscopy is very sensitive to electron correlation in two-dimensional (2D) systems: intensity modulation clearly identifies hierarchies of fractional quantum Hall states. We report measurements that reveal that the interaction between 2D electrons and a photoexcited valence-band hol...
