Optical Absorption in Incoherent and Coherent States of a Quantum Hall System
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 2018, Vol 15, Issue 0
Abstract
In connection with recent studies of extremely long-living spin-cyclotron excitations (actually magneto-excitons) in a quantum Hall electron gas, we discuss contribution to the light-absorption related to the presence of a magneto-exciton ensemble in this purely electronic system. Since the weakly interacting excitations have to obey the Bose-Einstein statistics, one can expect appearance of a coherent state in the ensemble. A comparative analysis of both incoherent and coherent cases is done. Conditions for a phase transition from the incoherent state to the coherent one are discussed.
