Impurity luminescence from a Laughlin 2D electron gas

Apal'kov V.M., Rashba E.I.

The spectrum of the impurity recombination radiation from a 2D electron gas is calculated in the spherical Haldane model for a filling factor *ν *= 1/3. The spectrum depends critically on the angular momentum of the system in its initial state. A change in the value of the angular momentum may cause abrupt changes in the emission spectrum as a function of the parameters of the system. The factors which determine the intensity of the line corresponding to the transition to the ground state of the system are studied. The position and intensity of the Auger satellites are also studied.
