Navier-Stokes Equations for Low-Temperature One-Dimensional Fluids
Andrew Urichuk, Stefano Scopa, Jacopo De Nardis
We consider one-dimensional interacting quantum fluids, such as the Lieb-Liniger gas. By computing the low-temperature limit of its (generalised) hydrodynamics we show how in this…

Analytical results for the low-temperature Drude weight of the XXZ spin chain
Andrew Urichuk, Jesko Sirker, Andreas Klümper
The spin- XXZ chain is an integrable lattice model and parts of its spin current can be protected by local conservation laws for anisotropies . In this case, the Drude…

The spin Drude weight of the XXZ chain and generalized hydrodynamics
A. Urichuk, Y. Oez, A. Klümper +1
Based on a generalized free energy we derive exact thermodynamic Bethe ansatz formulas for the expectation value of the spin current, the spin current-charge, charge-charge correla…
