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 …

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 …

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 …

Ultrafast photodoping of the Mott insulators, possessing strong correlation between
electronic and magnetic degrees of freedom, holds promise for launching an ultrafast …

We report a temperature-dependent optical spectroscopic study of the Heisenberg-Kitaev
magnet α-RuCl 3. Our measurements reveal anomalies in the optical response near the …

Recent optical conductivity measurements reveal the presence of Hubbard excitons in
certain Mott insulators. In light of these results, it is important to revisit the dynamics of these …

Fifteen years since its inception, the Kitaev model still boasts only a narrow group of material
realizations. The progress in studying and understanding one of them, lithium iridate Li 2 IrO …

The possibility of investigating the dynamics of solids on timescales faster than the
thermalization of the internal degrees of freedom has disclosed novel non-equilibrium …

The family of edge-sharing tricoordinated iridates and ruthenates has emerged in recent
years as a major platform for Kitaev spin-liquid physics, where spins fractionalize into …
