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…

Optical conductivity due to orbital polarons in systems with orbital degeneracy
Piotr Wróbel, Robert Eder, Andrzej M. Oleś
We consider the impact of orbital polarons in doped orbitally ordered systems on optical conductivity using the simplest generic model capturing the directional nature of either $t…
