Spin liquids are collective phases of quantum matter that have eluded discovery in
correlated magnetic materials for over half a century. Theoretical models of these enigmatic …

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 first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

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

A Majorana fermion is a fermionic particle that is its own antiparticle. Since the theoretical
discovery by Ettore Majorana in 1937, the exotic particle has long been searched in particle …

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 …

The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice
site. When it is doped with additional carriers, they are unstable to spin-fluctuation-mediated …

We investigate the generic features of the low energy dynamical spin structure factor of the
Kitaev honeycomb quantum spin liquid perturbed away from its exact soluble limit by …

The fractionalization of elementary excitations in quantum spin systems is a central theme in
current condensed matter physics. The Kitaev honeycomb spin model provides a prominent …

The search for fractionalization in quantum spin liquids largely relies on their decoupling
with the environment. However, the spin-lattice interaction is inevitable in a real setting …
