论文摘要
我们计算在零温度下以给定动量的玻色子数量的波动。我们表明，相反的动量之间的相关性是抑制弱相互作用的玻色系统中远程顺序的重要指纹，并且被抑制了，并且具有非零动量的玻色子数量的完整分布是指数的。但是，准统计酯的分布是准高斯。讨论了我们对最近冷原子实验的发现的实验相关性。
We compute the fluctuations of the number of bosons with a given momentum for the Tonks-Girardeau gas at zero temperature. We show that correlations between opposite momenta, which is an important fingerprint of long range order in weakly interacting Bose systems, are suppressed and that the full distribution of the number of bosons with non zero momentum is exponential. The distribution of the quasi-condensate is however quasi Gaussian. Experimental relevance of our findings for recent cold atoms experiments are discussed.
