论文摘要
我们研究了限制在格子电位的二维激发子，用于晶格位点的高填充物。我们表明，对于晶格深度的较小值，可能形成了准方酸盐，但是对于较大的晶格深度值，由于激子有效质量的增加，准惯性的临界相位空间密度迅速超过了我们的实验覆盖范围。另一方面，在晶格的深层晶格电位的状态下，在晶格站点强烈局部定位，我们证明了一系列独立的准准偏置，与莫特绝缘阶段不同。
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.
