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 …

This is an introductory review of the physics of quantum spin liquid states. Quantum
magnetism is a rapidly evolving field, and recent developments reveal that the ground states …

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 …

Recently, realizations of Kitaev physics have been sought in the A 2 IrO 3 family of
honeycomb iridates, originating from oxygen-mediated exchange through edge-shared …

Recently, Co-based honeycomb magnets have been proposed as promising candidate
materials to host the Kitaev spin liquid (KSL) state. One of the front-runners is BaCo2 (AsO4) …

The description of quantized collective excitations stands as a landmark in the quantum
theory of condensed matter. A prominent example occurs in conventional magnets, which …

In transition-metal compounds with partially filled 4 d and 5 d shells spin–orbit
entanglement, electronic correlations, and crystal-field effects conspire to give rise to a …

We show how Raman spectroscopy can serve as a valuable tool for diagnosing quantum
spin liquids (QSL). We find that the Raman response of the gapless QSL of the Kitaev …

We present the theory of dynamical spin response for the Kitaev honeycomb model,
obtaining exact results for the structure factor (SF) in gapped and gapless, Abelian and non …
