Findings

Derived equations for critical temperatures of order parameters

Analyzed effects of correlations on phase transitions

Enhanced understanding of competing orders in cuprates

Abstract

The problem of competing orderings in the high-temperature cuprate materials is widely discussed for the last years. We present the mean-field approximation results for the spin-pseudospin model accounting for the on-site and inter-site correlations, the antiferromagnetic exchange coupling, the one- and two-particle transport. The explicit form of the equations for the critical temperatures of the most significant order parameters of the model are given.
