A high-resolution high-aperture optical system was used to visualize the real-space spreading of a dense ensemble of triplet cyclotron magnetoexcitons in a quantum Hall dielectric at a filling factor of ν = 2. Several resonances were detected in the photoinduced reflectance spectrum. A comparative analysis of the correlations between the transport properties and spatial coherence of the magnetoexciton condensate was performed.
Gorbunov et al. (Sun,) studied this question.
