Dynamical control over the confinement of spatially indirect excitons in electrostatic traps of GaAs coupled quantum wells
Mussie Beian, Suzanne Dang, Mathieu Alloing +6
We study spatially indirect excitons confined in a 10 m wide electrostatic trap of a GaAs double quantum well. We introduce a technique to control the amplitude of the electric…

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…
