Anomalous transport from hot quasiparticles in interacting spin chains

S Gopalakrishnan, R Vasseur - Reports on Progress in Physics, 2023 - iopscience.iop.org
Many experimentally relevant quantum spin chains are approximately integrable, and
support long-lived quasiparticle excitations. A canonical example of integrable model of …

Hydrodynamics of weak integrability breaking

A Bastianello, A De Luca… - Journal of Statistical …, 2021 - iopscience.iop.org
We review recent progress in understanding nearly integrable models within the framework

New Classical Integrable Systems from Generalized -Deformations

B Doyon, F Hübner, T Yoshimura - Physical Review Letters, 2024 - APS
We introduce and study a novel class of classical integrable many-body systems obtained
by generalized TT¯ deformations of free particles. Deformation terms are bilinears in …

We introduce a new universal framework describing fluctuations and correlations in
quantum and classical many-body systems, at the Euler hydrodynamic scale of space and …

Soliton gas: Theory, numerics, and experiments

P Suret, S Randoux, A Gelash, D Agafontsev, B Doyon… - Physical Review E, 2024 - APS
The concept of soliton gas was introduced in 1971 by Zakharov as an infinite collection of
weakly interacting solitons in the framework of Korteweg–de Vries (KdV) equation. In this …

Probing the local rapidity distribution of a one-dimensional bose gas

L Dubois, G Thémèze, F Nogrette, J Dubail… - Physical Review Letters, 2024 - APS
One-dimensional Bose gases with contact repulsive interactions are characterized by the
presence of infinite-lifetime quasiparticles whose momenta are called the “rapidities.” Here …

We investigate dynamical fluctuations of transferred magnetization in the one-dimensional
lattice Landau-Lifshitz magnet with uniaxial anisotropy, representing an emblematic model …

Hydrodynamic gauge fixing and higher order hydrodynamic expansion

J De Nardis, B Doyon - Journal of Physics A: Mathematical and …, 2023 - iopscience.iop.org
Hydrodynamics is a powerful emergent theory for the large-scale behaviours in many-body
systems, quantum or classical. It is a gradient series expansion, where different orders of …
