Using the theory of generalized hydrodynamics (GHD), we derive exact
Euler-scale dynamical two-point correlation functions of conserved
densities and currents in inhomogeneous, non-stationary states…

Abstract
In this paper we compute the leading correction to the bipartite entanglement entropy at large sub-system size, in integrable quantum field theories with diagonal scattering matrices. We…
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. We…

We investigate the quantum entanglement content of quasiparticle excitations in extended many-body systems. We show that such excitations give an additive contribution to the bipartite von Neumann…
Energy flow in non-equilibrium conformal field theory

We study the energy current and its fluctuations in quantum gapless 1d systems far from equilibrium modeled by conformal field theory, where two separated halves are prepared at distinct temperatures…

We provide a pedagogical review of the main ideas and results in non-equilibrium conformal field theory and connected subjects. These concern the understanding of quantum transport and its statistics…
Hydrodynamic Diffusion in Integrable Systems.
- J. De Nardis, D. Bernard, B. Doyon
- PhysicsPhysical Review Letters
- 6 July 2018
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.
Finite-Temperature Form Factors: a Review
- B. Doyon
- Physics
- 6 November 2006
We review the concept of finite-temperature form factor that was introduced re- cently by the author in the context of the Majorana theory. Finite-temperature form factors can be used to obtain…
