莫特绝缘体和Lieb-Liniger液体之间的失超

Quench between a Mott insulator and a Lieb-Liniger liquid

G. Goldstein, N. Andrei

摘要:

本文研究了莫特绝缘体和排斥性Lieb-Liniger液体之间的失超。我们发现明确的稳定状态时,很长一段时间已经过去后,淬火。它是由一个GGE密度矩阵,我们完全表征,计算准粒子密度描述的系统后,淬火。在长时间极限下,我们得到了局域三体密度密度关联函数的显式形式和密度密度关联函数的渐近长距离极限。后者被证明有一个高斯衰减在大的距离。

英文摘要:

In this work we study a quench between a Mott insulator and a repulsive Lieb-Liniger liquid. We find explicitly the stationary state when a long time has passed after the quench. It is given by a GGE density matrix which we completely characterize, calculating the quasiparticle density describing the system after the quench. In the long time limit we find an explicit form for the local three body density density density correlation function and the asymptotic long distance limit of the density density correlation function. The later is shown to have a Gaussian decay at large distances.
