We analyze those integrable statistical systems which originate from some relevant
perturbations of the minimal models of conformal field theories. When only massive …

Understanding the general principles underlying strongly interacting quantum states out of
equilibrium is one of the most important tasks of current theoretical physics. With …

Particular deformations of 2-D conformal field theory lead to integrable massive quantum
field theories. These can be characterized by the relativistic scattering data. We propose a …

The general properties of the factorized S-matrix in two-dimensional space-time are
considered. The relation between the factorization property of the scattering theory and the …

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 …

A system of equations is derived which must be satisfied by multiparticle matrix elements of
any local operator in field theories with soliton behaviour. Form factors of various operators …

The development of Relativistic Quantum Field Theory started in 1932 as a natural
extension of Quantum Mechanics to the relativistic domain [1]. The work of Feynman in the …

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 approach the study of non-integrable models of two-dimensional quantum field theory as
perturbations of the integrable ones. By exploiting the knowledge of the exact S-matrix and …

We use the thermodynamic Bethe ansatz to find the finite-size corrections to the ground-
state energy in an arbitrary (1+ 1)-dimensional purely elastic scattering theory. The leading …
