Critical and off-critical properties of the $X X Z$ chain in external homogeneous and staggered magnetic fields

F. C. Alcaraz, A. L. Malvezzi

The phase diagram of the $X X Z$ 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 $S = 3/2$ . The model has a tetracrit…
