Percolation model for structural phase transitions in Li $_{1 - x}$ H $_{x}$ IO $_{3}$ mixed crystals

P. H. L. Martins, J. A. Plascak, M. A. Pimenta

A percolation model is proposed to explain the structural phase transitions found in Li $_{1 - x}$ H $_{x}$ IO $_{3}$ mixed crystals as a function of the concentration parameter $x$ . The perc…

Phase Diagram and Critical Behavior of the Spin-1 Baxter-Wu Model with a Crystal Field

M. L. M. Costa, J. C. Xavier, J. A. Plascak

The phase diagram and critical behavior of the spin-1 Baxter-Wu model with a crystal field in two dimensions is explored by renormalization group, conventional finite-size scaling…
