Tetracritical behaviour in a spin-3/2 quantum chain

Condensed Matter 2007-05-23 v1

Abstract

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=3/2S=3/2. The model has a tetracritical point besides critical lines. The conformal anomaly and anomalous dimensions of some primary operators are calculated at the tetracritical point.
