Fingerprints of spin-orbital polarons and of their disorder in the photoemission spectra of doped Mott insulators with orbital degeneracy
Adolfo Avella, Andrzej M. Oleś, Peter Horsch
We explore the effects of disordered charged defects on the electronic excitations observed in the photoemission spectra of doped transition metal oxides in the Mott insulating reg…
The ab initio study of unconventional superconductivity in CeCoIn and FeSe
Andrzej Ptok, Konrad J. Kapcia, Przemysław Piekarz +1
Electronic structure and the shape of the Fermi surface are known to be of fundamental importance for the superconducting instability in real materials. We demonstrate that such an…
Orbital Physics
Andrzej M. Oleś
A tutorial introduction into the principles of Orbital Physics in strongly correlated transition metal oxides.
Order in Quantum Compass and Orbital Models
Piotr Czarnik, Jacek Dziarmaga, Andrzej M. Oleś
We investigate thermodynamic phase transitions in the compass model and in orbital model on an infinite square lattice by variational tensor network renormalization (VTNR) in…
Orbiton-magnon interplay in the spin-orbital polarons of KCuF3 and LaMnO3
Krzysztof Bieniasz, Mona Berciu, Andrzej M. Oleś
We present a quasi-analytical solution of a spin-orbital model of KCuF, using the variational method for Green's functions. By analyzing the spectra for different partial bos…
Emergent phases in a compass chain with multisite interactions
Wen-Long You, Cheng-Jie Zhang, Weihai Ni +2
We study a dimerised spin chain with biaxial magnetic interacting ions in the presence of an externally induced three-site interactions out of equilibrium. In the general case, the…
