Abstract
In this chapter, we study the relaxation dynamics of a quenched pair of 1D Bose gases with atom number imbalance. As demonstrated in the previous chapters, 1D Bose gases follow completely integrable dynamics via dephasing of their many-body eigenstates. For the imbalanced pair, we observe that this dephasing strongly depends on the choice of observable. In particular, we find that the dephasing can mimic thermalization if suitable initial conditions are imposed on the system.
