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…
First principles study of topological phase in chains of transition metals
Aksel Kobiałka, Przemysław Piekarz, Andrzej M. Oleś +1
Recent experiments have shown the signatures of Majorana bound states at the ends of magnetic chains deposited on a superconducting substrate. Here, we employ first principles calc…
Low-Temperature Phase of the CdReO Superconductor: Ab initio Phonon Calculations and Raman Scattering
Konrad J. Kapcia, Maureen Reedyk, Mojtaba Hajialamdari +5
Using an {\it ab initio} approach, we report a phonon soft mode in the tetragonal structure described by the space group of the K superconductor CdReO$_…
Spectral properties of spin-orbital polarons as a fingerprint of orbital order
Krzysztof Bieniasz, Mona Berciu, Andrzej M. Oleś
Transition metal oxides are a rich group of materials with very interesting physical properties that arise from the interplay of the charge, spin, orbital, and lattice degrees of f…
Criticality and factorization in the Heisenberg chain with Dzyaloshinskii-Moriya interaction
Tian-Cheng Yi, Wen-Long You, Ning Wu +1
In this work, we address the ground state properties of the anisotropic spin-1/2 Heisenberg XYZ chain under the interplay of magnetic fields and the Dzyaloshinskii-Moriya (DM) inte…
Orbital Symmetry and Orbital Excitations in High- Superconductors
Andrzej M. Oleś, Krzysztof Wohlfeld, Giniyat Khaliullin
We discuss a few possibilities of high- superconductivity with more than one orbital symmetry contributing to the pairing. First, we show that the high energies of orbital exc…
