ARPES study of orbital characters, symmetry breakings and pseudogaps in doped and pure Sr2IrO4
Alex Louat, Benjamin Lenz, Silke Biermann +6
Sr2IrO4 is characterized by a large spin-orbit coupling, which gives rise to bands with strongly entangled spin and orbital characters, called J=1/2 and J=3/2. We use light-polariz…
Magnetization density distribution of SrIrO: Deviation from a local picture
Jaehong Jeong, Benjamin Lenz, Arsen Gukasov +10
iridium oxides are of huge interest due to the potential for new quantum states driven by strong spin-orbit coupling. The strontium iridate SrIrO is particularly in th…
Spectral functions of SrIrO: theory versus experiment
Benjamin Lenz, Cyril Martins, Silke Biermann
The spin-orbit Mott insulator SrIrO has attracted a lot of interest in recent years from theory and experiment due to its close connection to isostructural high-tempera…
Non-local Coulomb correlations in pure and electron-doped : spectral functions, Fermi surface and pseudogap-like spectral weight distributions from oriented cluster dynamical mean field theory
Cyril Martins, Benjamin Lenz, Luca Perfetti +3
We address the role of non-local Coulomb correlations and short-range magnetic fluctuations in the high-temperature phase of SrIrO within state-of-the-art spectroscopic and…
Coulomb Correlations in 4d and 5d Oxides from First Principles - or How Spin-Orbit Materials choose their Effective Orbital Degeneracies
Cyril Martins, Markus Aichhorn, Silke Biermann
The interplay of spin-orbit interactions and Coulomb correlations has become a hot topic in condensed matter theory. Here, we review recent advances in dynamical mean-field theory-…
