Temporal Coherence of Spatially Indirect Excitons across Bose-Einstein Condensation: the Role of Free Carriers
Romain Anankine, Suzanne Dang, Mussie Beian +4
We study the time coherence of the photoluminescence radiated by spatially indirect excitons confined in a 10 m electrostatic trap. Above a critical temperature of 1 Kelvin, we…
Quantized Vortices and Four-Component Superfluidity of Semiconductor Excitons
Romain Anankine, Mussie Beian, Suzanne Dang +6
We study spatially indirect excitons of GaAs quantum wells, confined in a 10 microns electrostatic trap. Below a critical temperature of about 1 Kelvin, we detect macroscopic spati…
Spectroscopic Signatures for the Dark Bose-Einstein Condensation of Spatially Indirect Excitons
Mussie Beian, Mathieu Alloing, Romain Anankine +4
We study semiconductor excitons confined in an electrostatic trap of a GaAs bilayer heterostructure. We evidence that optically bright excitonic states are strongly depleted while…
Evidence for a Bose-Einstein condensate of excitons
Mathieu Alloing, Mussie Beian, Maciej Lewenstein +6
The demonstration of Bose-Einstein condensation in atomic gases at micro-Kelvin temperatures is a striking landmark while its evidence for semiconductor excitons still is a long-aw…
