Thermodynamic evidence for a field-angle-dependent Majorana gap in a Kitaev spin liquid

O. Tanaka et al.

Summary: By measuring the heat capacity of alpha-RuCl3 under different magnetic field directions, this study reveals strongly angle-dependent low-energy excitations in the material. These findings are consistent with the characteristics of itinerant Majorana fermions in the Kitaev model. Furthermore, the changes in edge transport correspond to the opening and closing of the bulk gap according to the magnetic field direction, and the absence of the quantum thermal Hall effect at higher magnetic fields suggests a nematic quantum spin liquid state with two-fold rotational symmetry.

Thermal Interferometry of Anyons in Spin Liquids

Zezhu Wei et al.

Summary: The use of heat transport interferometry can reveal anyonic statistics in charge insulators, even in the absence of charged excitations. By studying the heat transport through different interferometer geometries in Kitaev spin liquids, such as Fabry-Perot and Mach-Zehnder, drastically different behaviors can be observed, demonstrating the effectiveness of this method.

Oscillations of the thermal conductivity in the spin-liquid state of α-RuCl3

Peter Czajka et al.

Summary: Magnetic spin liquids cannot achieve magnetic order even at millikelvin temperatures due to conflicting constraints on each spin, leading to intense interest in the resulting quantum spin-liquid state with unusual excitations; Observations of oscillations in the thermal conductivity of alpha-RuCl3 in a specific magnetic field range reveal periodic behavior, closely related to the temperature-induced exponential decrease in oscillation amplitude and emergence of anomalous planar thermal Hall conductivity above approximately 2 K.

Scanning Tunneling Microscopy as a Single Majorana Detector of Kitaev's Chiral Spin Liquid

Masafumi Udagawa et al.

Summary: In this study, a local detection scheme for the Majorana zero mode (MZM) carried by a vison in Kitaev's chiral spin liquid (CSL) using scanning tunneling microscopy (STM) is proposed. By introducing a single Majorana into the system through hole-charge injection, the Majorana interacts with the MZM to form a stable composite object, leading to split peaks in the differential conductance that are comparable to the Majorana gap in CSL and observable in experiments.

Sign Structure of Thermal Hall Conductivity and Topological Magnons for In-Plane Field Polarized Kitaev Magnets

Li Ern Chern et al.

Summary: The appearance of half-quantized thermal Hall conductivity in alpha-RuCl3 with in-plane magnetic fields is taken as evidence for the Kitaev spin liquid. The sign structure of the thermal Hall conductivity aligns with predictions from the Kitaev honeycomb model, but quantization at low temperatures is needed for further confirmation.

Ryunosuke Takahashi et al.

Summary: The ultrafast demagnetization of NiCo2O4 epitaxial thin films with perpendicular magnetic anisotropy was observed using a time-resolved magneto-optical Kerr effect microscope. The demagnetization time constant obtained was approximately 0.4 ps, significantly smaller than those reported for other halfmetallic oxides.

Half-integer quantized anomalous thermal Hall effect in the Kitaev material candidate α-RuCl3

T. Yokoi et al.

Summary: Recent reports have shown the presence of half-integer thermal quantum Hall conductance in the two-dimensional honeycomb material alpha-RuCl3, even in magnetic fields without out-of-plane components. The measured field-angular variation of the quantized thermal Hall conductance in alpha-RuCl3 has the same sign structure as the topological Chern number of the pure Kitaev spin liquid, indicating that the non-Abelian topological order persists in the presence of non-Kitaev interactions.

Role of Majorana fermions in spin transport of anisotropic Kitaev model

Hirokazu Taguchi et al.

Summary: In this study, the impact of anisotropy on spin propagation in a quantum spin Kitaev model with zigzag edges was investigated. It was found that for small anisotropy, the spin propagation velocity matches the group velocity of itinerant Majorana fermions, while in a gapped system with large anisotropy, spin propagation is strongly suppressed. The study also addressed spin transport in junction systems described by Kitaev models with different anisotropies.

Field-angle dependence of thermal Hall conductivity in a magnetically ordered Kitaev-Heisenberg system

Shinnosuke Koyama et al.

Summary: The study on magnetic excitations and thermal Hall effect on the Kitaev-Heisenberg model reveals that the thermal Hall conductivity is sensitive to the spin ordered pattern and excitation spectra, and can be enhanced under certain conditions. Additionally, a common feature in the field-angle dependence is found, with the conductivity vanishing on planes spanned by the spin axes.

Majorana correlations in the Kitaev model with ordered-flux structures

Akihisa Koga et al.

Summary: Researchers investigated the effects of flux configurations on emergent Majorana fermions in the S = 1/2 Kitaev model on a honeycomb lattice. They found that periodically arranged flux configurations result in low-energy excitations that are distinctly different from the flux-free state. The study's findings could be crucial in controlling the motion of Majorana fermions and spin excitations in Kitaev candidate materials.

Topological magnons for thermal Hall transport in frustrated magnets with bond-dependent interactions

Emily Z. Zhang et al.

Summary: Thermal transport in topologically-ordered phases provides valuable insights by detecting charge-neutral quasiparticles that do not couple directly to electromagnetic probes. The half-quantized thermal Hall conductivity observed in alpha-RuCl3 under external magnetic fields is evidence of the presence of the non-Abelian Kitaev spin liquid. In the case of tilted magnetic fields, the plateau-like behavior and sign change of the thermal Hall conductivity arise in the partially polarized state.
