Entangled Spin-Orbital Phases in the d$^9$ Model

Strongly Correlated Electrons 2022-01-25 v1

Abstract

We investigate the phase diagrams of the spin-orbital d9d^9 Kugel-Khomskii model for a bilayer and a monolayer square lattice using Bethe-Peierls-Weiss method. For a bilayer we obtain valence bond phases with interlayer singlets, with alternating planar singlets, and two entangled spin-orbital (ESO) phases, in addition to the antiferromagnetic and ferromagnetic order. Possibility of such entangled phases in a monolayer is under investigation at present.
