在谐振势阱中，通过双光子共振激发Cu 2 O，在2K下产生了高密度冷激子气体.当激子密度超过10（17）cm（-3）时，在势阱底部观察到强定域光信号。玻色子激发的激子从陷阱边缘底部的可能性进行了讨论与光信号的起源。(c)2004 Elsevier B. V.保留所有权利。
A high-density cold exciton gas is generated in a harmonic potential trap by two-photon resonance excitation of Cu2O at 2 K. Strongly localized light signal is observed at the bottom of the potential trap when the exciton density exceeds 10(17) cm(-3). The possibility of bosonic stimulation of excitons from the trap rim to the bottom is discussed in connection with the origin of the light signal. (c) 2004 Elsevier B.V. All rights reserved.
