As we begin to reach the limits of classical computing, quantum computing has emerged as
a technology that has captured the imagination of the scientific world. While for many years …

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 quantum Hall effect in two-dimensional electron gases involves the flow of topologically
protected dissipationless charge currents along the edges of a sample. Integer or fractional …

At sufficiently low temperatures, magnetic materials often enter correlated phases hosting
collective, coherent magnetic excitations such as magnons or triplons. Drawing on the …

Spin liquids are collective phases of quantum matter that have eluded discovery in
correlated magnetic materials for over half a century. Theoretical models of these enigmatic …

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 …

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 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 …

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 …

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 …
