Abstract

A high-aperture optical system is used to visualize the spatial spreading of a dense ensemble of spin cyclotron magnetoexcitons in a quantum Hall dielectric at a filling factor ν = 2 (a state of the integer quantum Hall effect). It has been found that the ability to propagate in a nondiffusive manner over macroscopic distances is inherent not only to excitons with a momentum on the order of the reciprocal magnetic length, which form a coherent magnetoexciton condensate, but also to excitons with momenta close to zero.
