Dynamics of one dimensional quantum gases are now a active field of research both experimental and theoretical. We aim to study dynamics of relaxation of strongly interacting gas of bosons using Lieb-Liniger model. Due to integrability of this model, the long time state of the system is expected to be not the usual thermal Gibbs distribution but rather a peculiar Generalised Gibbs state with memory of the initial values of the conserved quantities. We will calculate observables in this state providing predictions for experiments. Next we will consider time scales on which such a Generalised Gibbs state is established.

一维量子气体动力学目前是一个活跃的实验和理论研究领域。利用Lieb-Liniger模型研究了玻色子强相互作用气体的驰豫动力学。由于该模型的可积性，预计系统的长时间态不是通常的热Gibbs分布，而是一种具有守恒量初值记忆的特殊的广义Gibbs态。我们将计算这种状态下的可观量，为实验提供预测。接下来，我们将考虑建立这种广义吉布斯状态的时间尺度。
