在静电阱中的间接激子气体中观察到凝聚。成像和干涉测量检测到激子凝聚在陷阱底部和激子自发相干出现随着温度的降低。在低于约1 K的温度下，观察到玻色-爱因斯坦凝聚的直接特征，即相干性在整个云上的延伸。
Condensation is observed in a gas of indirect excitons confined in an electrostatic trap. Imaging and interferometric measurements detect that excitons condense at the trap bottom and exciton spontaneous coherence emerges with lowering temperature. Below a temperature of about 1 K, the direct signature of Bose-Einstein condensation, the extension of coherence over the entire cloud, is observed.
