We review the recent advances and current challenges in the field of strong spin-orbit
coupled Kitaev materials, with a particular emphasis on the physics beyond the exactly …

Quantum spin liquids may be considered'quantum disordered'ground states of spin systems,
in which zero-point fluctuations are so strong that they prevent conventional magnetic long …

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 …

The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

Quantum spin liquids have fascinated condensed matter physicists for decades because of
their unusual properties such as spin fractionalization and long-range entanglement. Unlike …

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 …

The layered honeycomb magnet α-RuCl 3 has been proposed as a candidate to realize a
Kitaev spin model with strongly frustrated, bond-dependent, anisotropic interactions …

We examine the role of spin-orbit coupling in the electronic structure of α-RuCl 3, in which
Ru ions in 4 d 5 configuration form a honeycomb lattice. Our x-ray absorption spectroscopy …

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 …

The combination of electronic correlation and spin-orbit coupling is thought to precipitate a
variety of highly unusual electronic phases in solids, including topological and quantum spin …
