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.

一维量子气体的动力学现在是研究的主动研究领域，既有实验性和理论性）。我们旨在研究使用Lieb-Liniger模型的强烈相互作用气体放松的动力学。由于该模型的整合性，预计系统的长时间状态不是通常的热吉布斯分布，而是具有奇特的广义吉布斯状态，并记忆了保守数量的初始值。我们将在此状态下计算可观察到的实验预测。接下来，我们将考虑建立这种广义吉布斯状态的时间尺度。
