Quantum quenches to the attractive one-dimensional Bose gas: exact results
We study quantum quenches to the one-dimensional Bose gas with attractive interactions in the case when the initial state is an ideal one-dimensional Bose condensate. We focus on properties of the stationary state reached at late times after the quench. This displays a finite density of multi-par...

We study quantum quenches to the one-dimensional Bose gas with attractive
interactions in the case when the initial state is an ideal one-dimensional
Bose condensate. We focus on properties of the stationary state reached at late
times after the quench. This displays a finite density of multi-particle bound
states, whose rapidity distribution is determined exactly by means of the
quench action method. We discuss the relevance of the multi-particle bound
states for the physical properties of the system, computing in particular the
stationary value of the local pair correlation function $g_2$. |
