Bose-Einstein condensation in nonequilibrium systems

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The properties of quantum statistically degenerate systems of Bosons which are created by an external pump field and decay within a finite lifetime are investigated by means of a Green's function treatment. These investigations help to understand the physical properties of such condensed Bose-systems as excitons, excitonic molecules and spin aligned hydrogen atoms. As an example, recent experiments by Hulin et al. on degenerate excitons in Cu2O are analyzed and a condensate fraction of about 5% is obtained.
