TL;DR: It is demonstrated that α-RuCl_{3} undergoes a quantum phase transition to a QSL in a magnetic field of 7.5 T applied in the ab plane and that this high-field QSL phase has gapless spin excitations over a field range up to 16 T.

TL;DR: An effective-spin model in the strong-coupling limit is derived based on energy bands obtained from first-principles calculations, and it is found that the anisotropic Kitaev interaction K term and the isotropic antiferromagnetic off-diagonal exchange interaction Γ term are significantly larger than the Heisenberg exchange coupling J term.

TL;DR: In this article, the existence of topological edge states at the periphery of single-layer vertices of a graphitized transition metal dichalcogenide was confirmed and a bulk band gap at the Fermi level and insulating behaviors were also found in single layer vertices at low temperature.

TL;DR: Comprehensive results identifying the ground state of a triangular-lattice structured YbZnGaO_{4} as a spin glass are reported, including no long-range magnetic order, prominent broad excitation continua, and the absence of magnetic thermal conductivity.

TL;DR: The authors' experiments clearly show a field-induced phase transition occurring at μ_{0}H_{c}≈7.5 T, above which the magnetic order is completely suppressed, which puts a strong constraint on the nature of the high-field phase of α-RuCl_{3}.
