Symmetry Classes of Spin and Orbital Ordered States in a t2g Hubbard Model on a Two-dimensional Squar Lattice

Abstract

This paper presents symmetry classes of the Hartree-Fock (HF) solutions of spin and orbital ordered states in a t2g Hubbard model on a two-dimensional square lattice. Using a group theoretical bifurcation theory of the Hartree-Fock equation, we obtained many types of broken symmetry solutions which bifurcate from the normal state through one step transition… (More)
