The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

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 …

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 …

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 examine the role of spin-orbit coupling in the electronic structure of α-RuCl 3, in which
Ru ions in 4 d 5 configuration form a honeycomb lattice. Our x-ray absorption spectroscopy …

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 …

We report magnetic and thermodynamic properties of single crystal α-RuCl 3, in which the
Ru 3+(4 d 5) ion is in its low spin state and forms a honeycomb lattice. Two features are …

We discuss phenomena arising from the combined influence of electron correlation and spin-
orbit coupling (SOC), with an emphasis on emergent quantum phases and transitions in …

In this study, we reanalyze the magnetic interactions in the Kitaev spin-liquid candidate
materials Na 2 IrO 3, α-RuCl 3, and α-Li 2 IrO 3 using nonperturbative exact diagonalization …
