Title Bound states stabilization and generalized hydrodynamics in a one-dimensional attractive Bose gas
Abstract Ultracold quantum gases provide a versatile platform for exploring strong interactions and non-equilibrium phases with no equilibrium counterparts. These phenomena often surpass the computational reach of traditional numerical methods, necessitating innovative approaches. In this talk, I will discuss the experimental realization of the attractive one-dimensional Bose gas in highly non-equilibrium states, stabilized by approximate integrability. I will also introduce the theoretical framework of generalized hydrodynamics, a powerful tool for nearly-integrable systems that enables precise quantitative descriptions of these exotic phases.
