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…
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…
