TL;DR: In this article, the authors present a framework for studying transport in integrable systems: hydrodynamics with infinitely many conservation laws, and apply it to the description of energy transport between heat baths, and provide a full description of the current-carrying nonequilibrium steady state and the transition regions in a family of models including the Lieb-Liniger model of interacting Bose gases.

TL;DR: In this article, the leading correction to the bipartite entanglement entropy at large sub-system size, in integrable quantum field theories with diagonal scattering matrices, is computed.

TL;DR: In this article, it was shown that the Renyi entanglement entropy of a region of large size l in a one-dimensional critical model whose ground state breaks conformal invariance (such as in those described by non-unitary conformal field theories), behaves as ceff(n+1)/2n log(L), where ceff=c-24Delta > 0 is the effective central charge, c (which may be negative) is the central charge of the conformal fields theory and Delta < 0, the lowest holomorphic conformal dimension in the theory

TL;DR: In this paper, the authors apply the thermodynamic Bethe Ansatz to investigate the high energy behavior of a class of scattering matrices which have recently been proposed to describe the Homogeneous sine-Gordon models related to simply laced Lie algebras.

TL;DR: In this paper, a lattice version of the Yang-Lee model with a non-Hermitian quantum spin chain Hamiltonian was investigated and a new way to implement -symmetry on the lattice was proposed, which serves to guarantee the reality of the spectrum in certain regions of values of the coupling constants.
