The 1/2-XXZ spin-chain at finite magnetic field: Crossover phenomena driven by temperature
A. Klümper, J. R. Reyes Martínez, C. Scheeren +1
We investigate the asymptotic behaviour of spin-spin correlation functions for the integrable Heisenberg chain. To this end we use the Quantum Transfer Matrix (QTM) technique devel…
Multi-spin correlation functions for the Z-Invariant Ising model
J. R. Reyes Martinez
Continuing our work hep-th/9609135 where a explicit formula for the two-point functions of the two dimensional Z-invariant Ising model were found. I obtain here different results f…
Correlation functions for the Z-invariant Ising model
J. R. Reyes Martínez
The correlation functions of the Z-invariant Ising model are calculated explicitly using the Vertex Operators language developed by the Kyoto school.
Theory of Superselection Sectors for Generalized Ising models
J. R. Reyes Martínez
We apply the theory of superselection sectors in the same way as done by G.Mack and V.Schomerus for the Ising model to generalizations of this model described by J.Fröhlich and T.K…
