Temperature driven crossover phenomena in the correlation lengths of the one-dimensional t-J model
J. Sirker, A. Klümper
We describe a modified transfer matrix renormalization group (TMRG) algorithm and apply it to calculate thermodynamic properties of the one-dimensional t-J model. At the supersymme…

Ground-state properties of two-dimensional dimerized Heisenberg models
J. Sirker, A. Klümper, K. Hamacher
The purpose of this paper is to investigate the ground-state properties of two-dimensional Heisenberg models on a square lattice with a given dimerization. Our aim is threefold: Fi…
