High-resolution thermal expansion and magnetostriction measurements were performed on single crystals of $\ensuremath{\alpha}\ensuremath{-}{\mathrm{RuCl}}_{3}$ in magnetic fields applied parallel to the Ru-Ru bonds. The length changes were measured in the direction perpendicular to the honeycomb planes. Our data show clear thermodynamic characteristics for the field-induced phase transition at the critical field ${\ensuremath{\mu}}_{0}{H}_{\mathrm{c}1}=7.8(2)\phantom{\rule{0.16em}{0ex}}\mathrm…

Disorder, Low-Energy Excitations, and Topology in the Kitaev Spin Liquid.

The Kitaev model is a fascinating example of an exactly solvable model displaying a spin-liquid ground state in two dimensions. However, deviations from the original Kitaev model are expected to

On the proximate Kitaev quantum-spin liquid α-RuCl3: thermodynamics, excitations and continua

The main aim of this review is to summarize experimental evidence obtained by THz spectroscopy and utilizing heat-capacity experiments, which point to the existence of fractionalized excitations in the spin-liquid state, which in -RuCl3 exists at temperatures just above the onset of magnetic order or at in-plane magnetic fields just beyond the quantum-critical point where antiferromagnetic order becomes suppressed.

Nesting instability of gapless U(1) spin liquids with spinon Fermi pockets in two dimensions

Quantum spin liquids are exotic states of matter that may be realized in frustrated quantum magnets and feature fractionalized excitations and emergent gauge fields. Here, we consider a gapless U(1)

Magnon dispersion and dynamic spin response in three-dimensional spin models for α−RuCl3

In the search for experimental realizations of bond-anisotropic Kitaev interactions and resulting spin-liquid phases, the layered magnet $\ensuremath{\alpha}\text{\ensuremath{-}}{\mathrm{RuCl}}_{3}$

Magnon bound states versus anyonic Majorana excitations in the Kitaev honeycomb magnet α-RuCl3

Evidence for fractionalized quasiparticles is found by studying magnetic excitations across the field-temperature phase diagram for α-RuCl3, a Kitaev honeycomb material that has properties consistent with predictions of a phase hosting fractionalization Majorana fermions but that could also be explained by conventional magneticexcitations.
