Entangled spin-orbital phases in the bilayer Kugel-Khomskii model
Wojciech Brzezicki, Andrzej M. Oleś
We derive the Kugel-Khomskii spin-orbital (SO) model for a bilayer and investigate its phase diagram depending on Hund's exchange and the orbital splitting . In th…

Hidden dimer order in the quantum compass model
Wojciech Brzezicki, Andrzej M. Oleś
We introduce an exact spin transformation that maps frustrated Z_{i,j}Z_{i,j+1} and X_{i,j}X_{i+1,j} spin interactions along the rows and columns of the quantum compass model (QCM)…
