Magnetism in two-dimensional (2D) van der Waals (vdW) materials has recently emerged as
one of the most promising areas in condensed matter research, with many exciting emerging …

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 …

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 …

In the class of materials called spin liquids,–, a magnetically ordered state cannot be
attained even at millikelvin temperatures because of conflicting constraints on each spin; for …

Half-integer thermal quantum Hall conductance has recently been reported for the two-
dimensional honeycomb material α-RuCl3. We found that the half-integer thermal Hall …

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 …

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 …

Spin-orbit coupled honeycomb magnets with the Kitaev interaction have received a lot of
attention due to their potential of hosting exotic quantum states including quantum spin …

We argue that several empirical constraints strongly restrict parameters of the effective
microscopic spin model describing α-RuCl 3. In particular, such constraints dictate a …
