Résumé |
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.
