Following on from our recent work, we investigate a stochastic approach to non-equilibrium quantum spin systems. We show how the method can be applied to a variety of physical observables and for different initial conditions. We provide exact formula

Non-Equilibrium Conformal Field Theories with Impurities

Autor: Bernard, D., Doyon, B., Viti, J.

Publikováno v: J.Phys. A: 48 (2015) 05FT01

We present a construction of non-equilibrium steady states within conformal field theory. These states sustain energy flows between two quantum systems, initially prepared at different temperatures, whose dynamical properties are represented by two,

Form factors of branch-point twist fields in quantum integrable models and entanglement entropy

Autor: Cardy, J. L., Castro-Alvaredo, O. A., Doyon, B.

Publikováno v: J. Stat. Phys.130:129-168, 2008

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 find a remarkably universal result, depending only on the parti

Fermion Schwinger's function for the SU(2)-Thirring model

Autor: Doyon, B., Lukyanov, S.

Publikováno v: Nucl.Phys. B644 (2002) 451-475

We study the Euclidean two-point function of Fermi fields in the SU(2)-Thirring model on the whole distance (energy) scale. We perform perturbative and renormalization group analyses to obtain the short-distance asymptotics, and numerically evaluate

Unstable particles rarely feature in conjunction with integrability in 1+1D quantum field theory. However, the family of homogenous sine-Gordon models provides a rare example where both stable and unstable bound states are present in the spectrum whi
