Interplay of Spin-Orbit Coupling and Electron Correlations in Iridates

Más información sobre el libro

The examination focuses on 5d transition metal oxides, particularly iridates, revealing their unique physical behaviors due to strong electron correlations and spin-orbit coupling. By analyzing two iridate compounds with structures akin to high Tc cuprates, the study aims to uncover novel physical phenomena. Utilizing a combination of density functional theory and many-body methods, it addresses key topics in the iridate community, including the insulating ground state, antiferromagnetic ordering, and the emergence of Fermi arcs in the pseudo-gap phase.
