Thermodynamics and Crossover Phenomena in the Correlation Lengths of the One-Dimensional t-J Model
J. Sirker, A. Klümper
We investigate the thermodynamics of the one-dimensional t-J model using transfer matrix renormalization group (TMRG) algorithms and present results for quantities like particle nu…

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…

Entropy Driven Dimerization in a One-Dimensional Spin-Orbital Model
J. Sirker, G. Khaliullin
We study a new version of the one-dimensional spin-orbital model with spins S=1 relevant to cubic vanadates. At small Hund's coupling J_H we discover dimerization in a pure electro…
