Repulsive to attractive interaction quenches for bosons in a one-dimensional trap — •Wladimir Tschischik, Roderich Moessner, and Masud Haque — Max-Planck-Institut für Physik komplexer Systeme, Dresden, Germany

We present a study of the non-equilibrium dynamics of attractively interacting bosons in a one-dimensional harmonic trap. We describe the physics in terms of many-body spectra. We focus on the highly excited `super-Tonks-Girardeau' state that is accessed through a sudden quench from a positive to a negative interaction. We describe both lattice (Bose-Hubbard) and continuum (Lieb-Liniger) cases.
