The approach to thermal equilibrium, or thermalization, in isolated quantum systems is
among the most fundamental problems in statistical physics. Recent theoretical studies have …

We consider the current operators of one-dimensional integrable models. These operators
describe the flow of the conserved charges of the models, and they play a central role in …

These notes are the write-up and extension of the lectures I gave over a few years for a class
on “Introduction to Bethe Ansatz” within the Ph. D. program in Statistical Physics at SISSA …

Michel Gaudin's book La fonction d'onde de Bethe is a uniquely influential masterpiece on
exactly solvable models of quantum mechanics and statistical physics. Available in English …

We give a pedagogical introduction to the methodology of the Quench Action, which is an
effective representation for the calculation of time-dependent expectation values of physical …

The purpose of this article is threefold. First, it provides the reader with a few useful and
efficient tools which should enable her/him to evaluate nontrivial determinants for the case …

[en] The Bethe ansatz method is widely used to investigate two-dimensional completely
integrable models. In the framework of the quantum inverse scattering method it has proved …

Exactly solvable models, that is, models with explicitly and completely diagonalizable
Hamiltonians are too few in number and insufficiently diverse to meet the requirements of …

Inspired by classical results in integrable boundary quantum field theory, we propose a
definition of integrable initial states for quantum quenches in lattice models. They are …

The quantum nonlinear Schrödinger equation (one dimensional Bose gas) is considered.
Classification of representations of Yangians with highest weight vector permits us to …
