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 …

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 honeycomb magnet α-RuCl3 has attracted considerable interest because it is proximate
to the Kitaev Hamiltonian whose excitations are Majoranas and vortices. The thermal Hall …

Understanding topological matter is an outstanding challenge across several disciplines of
physical science. Programmable quantum simulators have emerged as a powerful approach …

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 …

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 …

Finding new materials with antiferromagnetic (AFM) Kitaev interaction is an urgent issue for
quantum magnetism research. We conclude that Na 3 Co 2 SbO 6 and Na 2 Co 2 TeO 6 are …

Elementary excitations in entangled states such as quantum spin liquids may exhibit exotic
statistics different from those obeyed by fundamental bosons and fermions. Non-Abelian …

Layered α-RuCl3 is a promising material to potentially realize the long-sought Kitaev
quantum spin liquid with fractionalized excitations. While evidence of this state has been …

As a candidate Kitaev material, Na 2 Co 2 TeO 6 exhibits intriguing magnetism on a
honeycomb lattice that is believed to be C 3 symmetric. Here we report a neutron diffraction …
