Planar thermal Hall effect of topological bosons in the Kitaev magnet α-RuCl3
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 conductivity κxy of Majorana fermi...

Oscillations of the thermal conductivity in the spin-liquid state of α-RuCl3
In the class of materials called spin liquids1–3, a magnetically ordered state cannot be attained even at millikelvin temperatures because of conflicting constraints on each spin; for example, from geometric or e...

Open AccessThe range of non-Kitaev terms and fractional particles in α-RuCl3
Significant efforts have focused on the magnetic excitations of relativistic Mott insulators, predicted to realize the Kitaev quantum spin liquid (QSL). This exactly solvable model involves a highly entangled ...

Concept and realization of Kitaev quantum spin liquids
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 liquid (QSL) in the ground state. ...

Open AccessExcitations in the field-induced quantum spin liquid state of α-RuCl3
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 fluxes. Upon breaking of time-reversal s...

Open AccessAn NCN-pincer ligand dysprosium single-ion magnet showing magnetic relaxation via the second excited state
Single-molecule magnets are compounds that exhibit magnetic bistability purely of molecular origin. The control of anisotropy and suppression of quantum tunneling to obtain a comprehensive picture of the relax...

Open AccessVisualizing the chemistry and structure dynamics in lithium-ion batteries by in-situ neutron diffraction
We report an in-situ neutron diffraction study of a large format pouch battery cell. The succession of Li-Graphite intercalation phases was fully captured under an 1C charge-discharge condition (i.e., charge to f...

Quantum criticality and universal scaling of a quantum antiferromagnet
Quantum effects dominate the behaviour of many diverse materials. Of particular current interest are those systems in the vicinity of a quantum critical point (QCP). Their physical properties are predicted to ...
