Critical and off-critical properties of the chain in external homogeneous and staggered magnetic fields
F. C. Alcaraz, A. L. Malvezzi
The phase diagram of the chain under the influence of homogeneous and staggered magnetic fields is calculated. The model has a rich phase structure with three types of phases…

Tetracritical behaviour in a spin-3/2 quantum chain
A. Malvezzi
Finite-Size-Scaling and Conformal Invariance are used in order to find the phase diagram and critical exponents of a quantum spin chain with spin . The model has a tetracrit…
