Observation of Algebraic Time Order for Two-Dimensional Dipolar Excitons
S. Dang, M. Zamorano, S. Suffit +5
Emergence of algebraic quasi-long-range order is a key feature of superfluid phase transitions at two dimensions. For this reduced dimensionality interactions prevent Bose-Einstein…
Defect-Driven Superfluid Crossover for Two-Dimensional Dipolar Excitons Trapped at Thermodynamic Equilibrium
Suzanne Dang, Romain Anankine, Carmen Gomez +3
We study ultra-cold dipolar excitons confined in a 10m trap of a double GaAs quantum well. Based on the local density approximation, we unveil for the first time the equation of…
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…
