Generalised -deformations of classical free particles
Benjamin Doyon, Friedrich Hübner, Takato Yoshimura
Deformations of many-body Hamiltonians by certain products of conserved currents, referred to as -deformations, are known to preserve integrability. Generalised $T\bar{T}…
New classical integrable systems from generalized -deformations
Benjamin Doyon, Friedrich Hübner, Takato Yoshimura
We introduce and study a novel class of classical integrable many-body systems obtained by generalized -deformations of free particles. Deformation terms are bilinears in…
Emergence of hydrodynamic spatial long-range correlations in nonequilibrium many-body systems
Benjamin Doyon, Gabriele Perfetto, Tomohiro Sasamoto +1
At large scales of space and time, the nonequilibrium dynamics of local observables in extensive many-body systems is well described by hydrodynamics. At the Euler scale, one assum…
Ballistic macroscopic fluctuation theory
Benjamin Doyon, Gabriele Perfetto, Tomohiro Sasamoto +1
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 time. The f…
The Space of Integrable Systems from Generalised -Deformations
Benjamin Doyon, Joseph Durnin, Takato Yoshimura
We introduce an extension of the generalised -deformation described by Smirnov-Zamolodchikov, to include the complete set of extensive charges. We show that this gives de…
Form factors and generalized hydrodynamics for integrable systems
Axel Cortés Cubero, Takato Yoshimura, Herbert Spohn
Our review covers microscopic foundations of generalized hydrodynamics (GHD). As one generic approach we develop form factor expansions, for ground states and generalized Gibbs ens…
Interplay between transport and quantum coherences in free fermionic systems
Tony Jin, Tristan Gautié, Alexandre Krajenbrink +2
We study the quench dynamics in free fermionic systems in the prototypical bipartitioning protocol obtained by joining two semi-infinite subsystems prepared in different states, ai…
-deformed conformal field theories out of equilibrium
Marko Medenjak, Giuseppe Policastro, Takato Yoshimura
We consider the out-of-equilibrium transport in -deformed (1+1)-dimension conformal field theories (CFTs). The theories admit two disparate approaches, integrability and…
Thermal transport in -deformed conformal field theories: from integrability to holography
Marko Medenjak, Giuseppe Policastro, Takato Yoshimura
In this paper we consider the energy and momentum transport in (1+1)-dimension conformal field theories (CFTs) that are deformed by an irrelevant operator , using the int…
Collision rate ansatz for quantum integrable systems
Takato Yoshimura, Herbert Spohn
For quantum integrable systems the currents averaged with respect to a generalized Gibbs ensemble are revisited. An exact formula is known, which we call "collision rate ansatz". W…
Non-Hermitian quantum impurity systems in and out of equilibrium: noninteracting case
Takato Yoshimura, Kemal Bidzhiev, Hubert Saleur
We provide systematic analysis on a non-Hermitian PT -symmetric quantum impurity system both in and out of equilibrium, based on exact computations. In order to understand the inte…
Diffusion from Convection
Marko Medenjak, Jacopo De Nardis, Takato Yoshimura
We introduce non-trivial contributions to diffusion constant in generic many-body systems arising from quadratic fluctuations of ballistically propagating, i.e. convective, modes.…
Equations of state in generalized hydrodynamics
Dinh-Long Vu, Takato Yoshimura
We, for the first time, report a first-principle proof of the equations of state used in the hydrodynamic theory for integrable systems, termed generalized hydrodynamics (GHD). The…
Full counting statistics in the free Dirac theory
Takato Yoshimura
We study charge transport and fluctuations of the (3+1)-dimensional massive free Dirac theory. In particular, we focus on the steady state that emerges following a local quench whe…
Generalized hydrodynamics of classical integrable field theory: the sinh-Gordon model
Alvise Bastianello, Benjamin Doyon, Gerard Watts +1
Using generalized hydrodynamics (GHD), we develop the Euler hydrodynamics of classical integrable field theory. Classical field GHD is based on a known formalism for Gibbs ensemble…
Hydrodynamics of the interacting Bose gas in the Quantum Newton Cradle setup

Describing and understanding the motion of quantum gases out of equilibrium is one of the most important modern challenges for theorists. In the groundbreaking Quantum Newton Cradl…
Soliton gases and generalized hydrodynamics
Benjamin Doyon, Takato Yoshimura, Jean-Sébastien Caux
Dynamical equations in generalized hydrodynamics (GHD), a hydrodynamic theory for integrable quantum systems at the Euler scale, take a rather simple form, even though an infinite…
A geometric viewpoint on generalized hydrodynamics
Benjamin Doyon, Herbert Spohn, Takato Yoshimura
Generalized hydrodynamics (GHD) is a large-scale theory for the dynamics of many-body integrable systems. It consists of an infinite set of conservation laws for quasi-particles tr…
Large-scale description of interacting one-dimensional Bose gases: generalized hydrodynamics supersedes conventional hydrodynamics
Benjamin Doyon, Jérôme Dubail, Robert Konik +1
The theory of generalized hydrodynamics (GHD) was recently developed as a new tool for the study of inhomogeneous time evolution in many-body interacting systems with infinitely ma…
A note on generalized hydrodynamics: inhomogeneous fields and other concepts
Benjamin Doyon, Takato Yoshimura
Generalized hydrodynamics (GHD) was proposed recently as a formulation of hydrodynamics for integrable systems, taking into account infinitely-many conservation laws. In this note…

Olalla A. Castro-Alvaredo, Benjamin Doyon, Takato Yoshimura
Understanding the general principles underlying strongly interacting quantum states out of equilibrium is one of the most important tasks of current theoretical physics. With exper…
