The Ising Nematic in the J1–J2 Heisenberg Model on a Square Lattice in a Self-Consistent Spin-Wave Theory

A study is performed of Ising nematic ordering, the Ising nematic phase transition, and the temperature behavior of short-range order parameters in the Heisenberg quantum antiferromagnetic model with spin 1/2 on a two-dimensional square lattice, allowing for the exchange parameters of the first and...

Description
Summary:A study is performed of Ising nematic ordering, the Ising nematic phase transition, and the temperature behavior of short-range order parameters in the Heisenberg quantum antiferromagnetic model with spin 1/2 on a two-dimensional square lattice, allowing for the exchange parameters of the first and second neighbors. Two versions of the self-consistent spin–wave theory are considered: with and without auxiliary pseudofermions.
