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 …

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 …

Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

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 …

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 …

The celebrated Kitaev quantum spin liquid (QSL) is the paradigmatic example of a
topological magnet with emergent excitations in the form of Majorana Fermions and gauge …

In the recent years, the thermal Hall transport has risen as an important diagnosis of the
physical properties of the elementary excitations in various quantum materials, especially …

Quantum spin liquids are an exciting playground for exotic physical phenomena and
emergent many-body quantum states. The realization and discovery of quantum spin liquid …

In condensed matter physics there is a novel phase termed 'quantum spin liquid', in which
strong quantum fluctuations prevent long-range magnetic order from being estab lished, and …
