A quantum Ising-like spin-1 system with both dipole and quadrupole interactions is analyzed. Models of this type are interesting candidates to describe phase transitions in liquid crystals. The phase diagram as well as the thermodynamic potentials of the model are constructed by a recently formulated improved version of mean field theory.

Abstract
A quantum Ising-like spin-1 system with both dipole and quadrupole interactions is analyzed. Models of this type are interesting candidates to describe phase transitions in liquid crystals. The phase diagram as well as the thermodynamic potentials of the model are constructed by a recently formulated improved version of mean field theory.Pubblicazioni consigliate
