Polaron-driven switching of octupolar order in doped 5d double perovskite
Dario Fiore Mosca, Lorenzo Celiberti, Leonid V. Pourovskii +1
We investigate how doping-induced small polarons impact the low-temperature multipolar orders of the double perovskite BaCaOsO. By computing intersite exchange inter…

Hidden orders in spin-orbit entangled correlated insulators
Leonid V. Pourovskii, Dario Fiore Mosca, Lorenzo Celiberti +3
In many materials, ordered phases and their order parameters are easily characterized by standard experimental methods. "Hidden order" refers to a phase transition in which an orde…

Interplay of superexchange and vibronic effects in the hidden order of BaMgReO from first principles
Dario Fiore Mosca, Cesare Franchini, Leonid V. Pourovskii
The origin of the "hidden" quadrupolar and unconventional magnetic low-temperature orders observed in the spin-orbit double perovskite BaMgReO defies explanation through st…
