Spin-Orbital Entanglement Emerging from Frustration in the Kugel-Khomskii Model
W. Brzezicki, A. M. Oleś
We investigate the zero-temperature phase diagrams of the bilayer square-lattice Kugel-Khomskii () model involving entangled and singlet phases using mean-field cluster approa…

Noncollinear Magnetic Order Stabilized by Entangled Spin-Orbital Fluctuations
Wojciech Brzezicki, Jacek Dziarmaga, Andrzej M. Oleś
Quantum phase transitions in the two-dimensional Kugel-Khomski model on a square lattice are studied using the plaquette mean field theory and the entanglement renormalization ansa…

Entangled Spin-Orbital Phases in the d Model
Wojciech Brzezicki, Andrzej M. Oleś
We investigate the phase diagrams of the spin-orbital Kugel-Khomskii model for a bilayer and a monolayer square lattice using Bethe-Peierls-Weiss method. For a bilayer we obt…
