The Kitaev model is an exactly solvable S= 1/2 spin model on a 2D honeycomb lattice, in
which the spins fractionalize into Majorana fermions and form a topological quantum spin …

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 …

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 …

The celebrated Kitaev quantum spin liquid (QSL) is the paradigmatic example of a
topological magnet with emergent excitations in the form of Majorana Fermions and gauge …

It has been suggested that certain antiferromagnetic topological insulators contain axion
quasiparticles (AQs), and that such materials could be used to detect axion dark matter …

Quantum spin liquids (QSLs) are topologically ordered states of matter that host
fractionalized excitations. A particular route towards a QSL is via strongly bond-dependent …

Magnetic excitations in van der Waals (vdW) materials, especially in the two-dimensional
(2D) limit, are an exciting research topic from both the fundamental and applied …

We report on terahertz spectroscopy of quantum spin dynamics in α-RuCl 3, a system
proximate to the Kitaev honeycomb model, as a function of temperature and magnetic field …

Antiferromagnetically doped topological insulators (ATI) are among the candidates to host
dynamical axion fields and axion polaritons, weakly interacting quasiparticles that are …
