We theoretically investigate the non-equilibrium dynamics in a quenched pairof 1D Bose gases with density imbalance. We describe the system using itslow-energy effective theory, the Luttinger liquid model. In this framework thesystem shows strictly integrable relaxation dynamics via dephasing of itsapproximate many-body eigenstates. In the balanced case, this leads to thewell-known light-cone-like establishment of a prethermalized state, which canbe described by a generalized Gibbs ensemble. In the imbalanced case theintegrable dephasing leads to a state that, counter-intuitively, closelyresembles a thermal equilibrium state. The approach to this state ischaracterized by two separate light-cone dynamics with distinct characteristicvelocities. This behavior is rooted in the fact that in the imbalanced caseobservables are not aligned with the conserved quantities of the integrablesystem. We discuss a concrete experimental realization to study this effectusing matterwave interferometry and many-body revivals on an atom chip.
