Camille Lagoin, Stephan Suffit, Kenneth West, Kirk Baldwin, Loren Pfeiffer, Markus Holzmann, Francois Dubin

摘要:

我们研究二维激子局限在晶格势,高填充的晶格网站。我们表明,准凝聚可能形成小的晶格深度值,但对于较大的准凝聚的临界相空间密度迅速超过我们的实验范围,由于激子有效质量的增加。另一方面,在制度的深晶格势激子强烈本地化的晶格站点,我们表明,阵列的相位无关的准凝聚体,不同的莫特绝缘相,实现。

英文摘要:

We study two-dimensional excitons confined in a lattice potential, for high fillings of the lattice sites. We show that a quasi-condensate is possibly formed for small values of the lattice depth, but for larger ones the critical phase-space density for quasi-condensation rapidly exceeds our experimental reach, due to the increase of the excitons effective mass. On the other hand, in the regime of a deep lattice potential where excitons are strongly localised at the lattice sites, we show that an array of phase-independent quasi-condensates, different from a Mott insulating phase, is realised.
