Adiabatic formation of bound states in the 1d Bose gas

In this talk, I discuss the bound state formation in the 1d Bose gas out of equilibrium due to interaction changes from the repulsive to the attractive regime. In the case of adiabatic protocols, the populations of the bound states can be exactly determined thanks to a recently devised hydrodynamic approach to integrable models, known as Generalized Hydrodynamics. Applications to the state-of-the-arts cold atoms experiments are shortly discussed.
