Half-integer quantized anomalous thermal Hall effect in the Kitaev material -RuCl
T. Yokoi, S. Ma, Y. Kasahara +9
Heat transport mediated by Majorana edge modes in a magnetic insulator leads to a half-integer thermal quantum Hall conductance, which has recently been reported for the two-dimens…
Finite-Temperature Phase Transition to a Quantum Spin Liquid in a Three-Dimensional Kitaev Model on a Hyperhoneycomb Lattice
J. Nasu, T. Kaji, K. Matsuura +2
We present numerical evidence for the presence of a finite-temperature () phase transition separating paramagnet and quantum spin liquid in a three-dimensional variant of the Ki…
Majorana-fermion origin of the planar thermal Hall effect in the Kitaev magnet -RuCl
K. Imamura, S. Suetsugu, Y. Mizukami +11
The field-induced quantum disordered state of layered honeycomb magnet -RuCl is a prime candidate for Kitaev spin liquids hosting Majorana fermions and non-Abelian anyons.…
Majorana quantization and half-integer thermal quantum Hall effect in a Kitaev spin liquid
Y. Kasahara, T. Ohnishi, Y. Mizukami +9
The quantum Hall effect (QHE) in two-dimensional (2D) electron gases, which is one of the most striking phenomena in condensed matter physics, involves the topologically protected…
Doubly degenerate orbital system in honeycomb lattice: implication of orbital state in layered iron oxide
J. Nasu, A. Nagano, M. Naka +1
We study a doubly-degenerate orbital model on a honeycomb attice. This is a model for orbital states in multiferroic layered iron oxides. The classical and quantum models are analy…
Evidence for the first-order topological phase transition in a Kitaev spin liquid candidate -RuCl
S. Suetsugu, Y. Ukai, M. Shimomura +9
The Kitaev quantum spin liquid (QSL) on the two-dimensional honeycomb lattice epitomizes an entangled topological state, where the spins fractionalize into Majorana fermions. This…
