The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

In the past decade, resonant inelastic x-ray scattering (RIXS) has made remarkable progress
as a spectroscopic technique. This is a direct result of the availability of high-brilliance …

The exactly solvable Kitaev model on the honeycomb lattice has recently received
enormous attention linked to the hope of achieving novel spin-liquid states with …

Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one
of the most actively studied subjects in condensed matter physics, as correlations and SOC …

Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

Ni–Fe‐based oxides are among the most promising catalysts developed to date for the
bottleneck oxygen evolution reaction (OER) in water electrolysis. However, understanding …

Complex oxides with 4 d and 5 d transition-metal ions recently emerged as a new paradigm
in correlated electron physics, due to the interplay between spin–orbit coupling and electron …

The properties of transition metal compounds are largely determined by nontrivial interplay
of different degrees of freedom: charge, spin, lattice, and also orbital ones. Especially rich …

Topological insulators are characterized by a non-trivial band topology driven by the spin-
orbit coupling. To fully explore the fundamental science and application of topological …

This review addresses the method of explicit calculations of interatomic exchange
interactions of magnetic materials. This involves exchange mechanisms normally referred to …
