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 …

Two-dimensional (2D) materials exhibit a wide range of atomic structures, compositions, and
associated versatility of properties. Furthermore, for a given composition, a variety of …

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 …

A key feature of quantum spin liquids is the predicted formation of fractionalized excitations.
They are expected to produce changes in the physical response, providing a way to observe …

The material α-RuCl 3 has been the subject of intense scrutiny as a potential Kitaev
quantum spin liquid, predicted to display Majorana fermions as low-energy excitations. In …

Motivated by experimental studies that have found signatures of a quantum spin liquid
phase in organic crystals whose structure is well described by the two-dimensional …

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 …

The magnetism of Kitaev materials has been widely studied, but their charge properties and
the coupling to other degrees of freedom are less known. Here we investigate the charge …

We have investigated the sample dependence of the half-integer thermal Hall effect in α-
RuCl 3 under a magnetic field tilted 45∘ from the c axis to the a axis. We find that the sample …
