Generalized hydrodynamics with space-time inhomogeneous interactions

Understand

We provide a new hydrodynamic framework to describe out-of-equilibrium integrable systems with space-time inhomogeneous interactions.

• Our result builds up on the recently-introduced Generalized Hydrodynamics (GHD).
• The method allows to analytically describe the dynamics during generic space-time-dependent smooth modulations of the interactions.
• As a proof of concept, we study experimentally-motivated interaction quenches in the trapped interacting Bose gas, which cannot be treated with current analytical or numerical methods.
