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 …

Quantum spin liquids (QSLs) are topological states of matter exhibiting remarkable
properties such as the capacity to protect quantum information from decoherence. Whereas …

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 …

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 …

Heisenberg interactions are ubiquitous in magnetic materials and play a central role in
modelling and designing quantum magnets. Bond-directional interactions,, offer a novel …

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 …

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 …

Conventionally ordered magnets possess bosonic elementary excitations, called magnons.
By contrast, no magnetic insulators in more than one dimension are known whose …

Abstract Effects of spin–orbit interactions in condensed matter are an important and rapidly
evolving topic. Strong competition between spin–orbit, on-site Coulomb and crystalline …
