Emergent hydrodynamics in integrable quantum systems out of equilibrium
Understanding the general principles underlying strongly interacting quantum states out of equilibrium is one of the most important tasks of current theoretical physics. With experiments accessing…

  • 13 November 2017
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…
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…
Form Factors of Branch-Point Twist Fields in Quantum Integrable Models and Entanglement Entropy
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…
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…
Entanglement Content of Quasiparticle Excitations.
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…
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.
Non-Equilibrium Steady States in Conformal Field Theory
We present a construction of non-equilibrium steady states in one-dimensional quantum critical systems carrying energy and charge fluxes. This construction is based on a scattering approach within a…
Finite-Temperature Form Factors: a Review

  • 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…
Entanglement content of quantum particle excitations. III. Graph partition functions
We consider two measures of entanglement, the logarithmic negativity and the entanglement entropy, between regions of space in excited states of many-body systems formed by a finite number of…
