Deconfinement phase transition in a two-dimensional model of interacting plaquettes
A. Fledderjohann, A. Klümper, K. H. Mütter
A two-dimensional model of interacting plaquettes is studied by means of the real space renormalization group approach. Interactions between the plaquettes are mediated solely by s…
Real space renormalization group approach to the 2d antiferromagnetic Heisenberg model
A. Fledderjohann, A. Klümper, K. H. Mütter
The low energy behaviour of the 2d antiferromagnetic Heisenberg model is studied in the sector with total spins by means of a renormalization group procedure, which gener…
Short-distance thermal correlations in the XXZ chain
Herman E. Boos, Jens Damerau, Frank Göhmann +3
Recent studies have revealed much of the mathematical structure of the static correlation functions of the XXZ chain. Here we use the results of those studies in order to work out…
