Observation of Superfluorescence from a Spontaneous Coherence of Excitons in ZnTe Crystal: Evidence for Bose-Einstein Condensation of Excitons?
Superfluorescence Spontaneous Coherence Excitons ZnTe Crystal Bose-Einstein Condensation
2011/8/11
Abstract: Superfluorescence (SF) is the emission from a dense coherent system in population inversion, formed from an initially incoherent ensemble. This is characterised by an induction time (t_D) fo...
Excitons in Molecular Aggregates with Lévy Disorder: Anomalous Localization and Exchange Broadening of Optical Spectra
Excitons in Molecular Aggregates Lévy Disorder Anomalous Localization Exchange Broadening of Optical Spectra

We predict the existence of exchange broadening of optical lineshapes in disordered molecular
aggregates and a nonuniversal disorder scaling of the localization characteristics of the collective elec...
