本文研究了87Rb原子气体在简谐磁阱和光晶格周期势的联合势中的量子简并相变。对于高光学晶格势，我们观察到一个显着的变化，在系统的基态的人口的温度依赖性。实验结果与假设随后在单晶格位置形成准二维凝聚体的模型吻合得很好。
We study the phase transition of a gas of 87Rb atoms to quantum degeneracy in the combined potential of a harmonically confining magnetic trap and the periodic potential of an optical lattice. For high optical lattice potentials we observe a significant change in the temperature dependency of the population of the ground state of the system. The experimental results are in good agreement with a model assuming the subsequent formation of quasi-2D condensates in the single lattice sites.
