We theoretically investigate the effects of atom losses in the one-dimensional (1D) Bose gas with repulsive contact interactions, a famous quantum integrable system also known as the Lieb-Liniger gas. The generic case of K-body losses (K = 1,2,3,...) is considered. We assume that the loss rate is much smaller than the rate of intrinsic relaxation of the system, so that at any time the state of the system is captured by its rapidity distribution (or, equivalently, by a Generalized Gibbs Ensemble… Expand

Integrability breaking in the one-dimensional Bose gas: Atomic losses and energy loss.
This work sets up a framework for the exact computation of the losses of the canonical charges of the Lieb-Liniger model, and compute an exact result for the energy loss due to the local K-body processes, valid for arbitrary K. Expand

Sudden expansion of a one-dimensional bose gas from power-law traps.
The stationary phase and local density approximations are used and it is shown that the long-time asymptotic density profile and the momentum distribution of the gas are determined by the initial distribution of Bethe rapidities and hence can be obtained from the solutions to the Lieb-Liniger equations in the thermodynamic limit.
