Tuning Crystal Field Potential by Orbital Dilution in Oxides
Wojciech Brzezicki, Filomena Forte, Canio Noce +2
We investigate the interplay between Coulomb driven orbital order and octahedral distortions in strongly correlated Mott insulators due to orbital dilution, i.e., doping by metal i…
Non-Hermitian Topological End-Mode Lasing in Polariton Systems
Paolo Comaron, Vanik Shahnazaryan, Wojciech Brzezicki +2
We predict the existence of non-Hermitian topologically protected end states in a one-dimensional exciton-polariton condensate lattice, where topological transitions are driven by…
Hidden Chern number in one-dimensional non-Hermitian chiral-symmetric systems
Wojciech Brzezicki, Timo Hyart
We consider a class of one-dimensional non-Hermitian models with a special type of a chiral symmetry which is related to pseudo-Hermiticity. We show that the topology of a Hamilton…
Topological domain wall states in a non-symmorphic chiral chain
Wojciech Brzezicki, Timo Hyart
The Su-Schrieffer-Heeger (SSH) model, containing dimerized hopping and a constant onsite energy, has become a paradigmatic model for one-dimensional topological phases, soliton exc…
Spin, orbital and topological order in models of strongly correlated electrons
Wojciech Brzezicki
Different types of order are discussed in the context of strongly correlated transition metal oxides, involving pure compounds and and hybrids. Apar…
Anomalous Hall effect in antiferromagnetic/non-magnetic interfaces
Marco Asa, Carmine Autieri, Riccardo Pazzocco +6
We report a combined theoretical and experimental investigation of magnetic proximity and Hall transport in Pt/Cr bilayers. Density functional theory indicates that an interfacial…
