We discuss phenomena arising from the combined influence of electron correlation and spin-
orbit coupling (SOC), with an emphasis on emergent quantum phases and transitions in …

Magnetic topological semimetals (TSMs) are topological quantum materials with broken time-
reversal symmetry (TRS) and isolated nodal points or lines near the Fermi level. Their …

The pyrochlore-type iridium oxide Eu 2 Ir 2 O 7 exhibits a metal-insulator transition at 120 K,
accompanied by magnetic ordering. We used x-ray diffraction measurements with photon …

Using resonant magnetic x-ray scattering we address the unresolved nature of the magnetic
ground state and the low-energy effective Hamiltonian of Sm 2 Ir 2 O 7, a prototypical …

Magnetic fluctuations and electrons couple in intriguing ways in the vicinity of zero-

The interplay of spin–orbit coupling and Coulomb correlations has become a hot topic in
condensed matter theory and is especially important in 4d and 5d transition metal oxides …

Combining density functional theory (DFT) and embedded dynamical mean-field theory
(DMFT) methods, we study the metal-insulator transition in R 2 Ir 2 O 7 (R= Y, Eu, Sm, Nd …

Pyrochlore iridates have recently attracted growing interest in condensed matter physics
