摘要:

本文描述了一种基于Bethe变换的方法,从多重积分表示出发,导出了相互作用一维玻色气体中密度-密度关联函数在有限温度下的长距离渐近行为.我们计算的相关长度的热力学Bethe anesthetic型的非线性积分方程的解决方案。最后,我们建立了一个连接,在我们的方法与量子传输矩阵方法产生的相关长度的结果。

英文摘要:

We describe a Bethe ansatz based method to derive, starting from a multiple integral representation, the long-distance asymptotic behavior at finite temperature of the density-density correlation function in the interacting one-dimensional Bose gas. We compute the correlation lengths in terms of solutions of non-linear integral equations of the thermodynamic Bethe ansatz type. Finally, we establish a connection between the results obtained in our approach with the correlation lengths stemming from the quantum transfer matrix method.
