Abstract

We have performed a renormalization-group analysis of a system of Kosterlitz-Thouless-Berezinskii (KTB) layers coupled to each other by a Lawrence-Doniach-type term, in zero field. We derive the recursion relations for the case where the interlayer coupling is weak. We find that is relevant and study the crossover away from KTB behavior. We have calculated the shift in the critical temperature and the size of the narrow three-dimensional critical region.
