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 …

We review the recent advances and current challenges in the field of strong spin-orbit
coupled Kitaev materials, with a particular emphasis on the physics beyond the exactly …

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 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 …

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 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 …

α-RuCl 3 is a leading candidate material for the observation of physics related to the Kitaev
quantum spin liquid (QSL). By combined susceptibility, specific-heat, and nuclear-magnetic …

The properties of transition metal compounds are largely determined by nontrivial interplay
of different degrees of freedom: charge, spin, lattice, and also orbital ones. Especially rich …
