We derive a large-scale hydrodynamic equation, including diffusive and dissipative effects, for systems with generic static position-dependent driving forces coupling to local conserved quantities. We show that this equation predicts entropy increase and thermal states as the only stationary states. The equation applies to any hydrodynamic system with any number of local, parity and time-symmetric conserved quantities, in arbitrary dimension. It is fully expressed in terms of elements of an… Expand

Diffusion in generalized hydrodynamics and quasiparticle scattering
We extend beyond the Euler scales the hydrodynamic theory for quantum and classical integrable models developed in recent years, accounting for diffusive dynamics and local entropy production. WeExpand
Hydrodynamic Diffusion in Integrable Systems.
TLDR
It is shown that hydrodynamic diffusion is generically present in many-body, one-dimensional interacting quantum and classical integrable models, and extended to terms of Navier-Stokes type, which leads to positive entropy production and diffusive relaxation mechanisms. Expand
Solvable Hydrodynamics of Quantum Integrable Systems.
TLDR
Time evolution from local equilibria in quantum integrable models by solving a certain kinetic equation, the "Bethe-Boltzmann" equation satisfied by the local pseudomomentum density, is studied. Expand

We obtain the exact generalized hydrodynamics for the integrable Toda system. The Toda system can be seen in a dual way, both as a gas and as a chain. In the gas point of view, using the elastic andExpand
