The QCD spin chain S matrix
Changrim Ahn, Rafael I. Nepomechie, Junji Suzuki
Beisert et al. have identified an integrable SU(2,2) quantum spin chain which gives the one-loop anomalous dimensions of certain operators in large N QCD. We derive a set of nonlin…
Factorization of the finite temperature correlation functions of the XXZ chain in a magnetic field
Herman E. Boos, Frank Göhmann, Andreas Klümper +1
We present a conjecture for the density matrix of a finite segment of the XXZ chain coupled to a heat bath and to a constant longitudinal magnetic field. It states that the inhomog…
ABCD and ODEs
Patrick Dorey, Clare Dunning, Davide Masoero +2
We outline a relationship between conformal field theories and spectral problems of ordinary differential equations, and discuss its generalisation to models related to classical L…
Pseudo-differential equations, and the Bethe Ansatz for the classical Lie algebras
Patrick Dorey, Clare Dunning, Davide Masoero +2
The correspondence between ordinary differential equations and Bethe ansatz equations for integrable lattice models in their continuum limits is generalised to vertex models relate…
Finite size effects in the spin-1 XXZ and supersymmetric sine-Gordon models with Dirichlet boundary conditions
Changrim Ahn, Rafael I. Nepomechie, Junji Suzuki
Starting from the Bethe Ansatz solution of the open integrable spin-1 XXZ quantum spin chain with diagonal boundary terms, we derive a set of nonlinear integral equations (NLIEs),…
Exact finite size spectrum in super sine-Gordon model
Arpad Hegedus, Francesco Ravanini, Junji Suzuki
We present the coupled nonlinear integral equations (NLIE) governing the finite size effects in N=1 super sine-Gordon model for the vacuum as well as for the excited states. Their…
