Effective model with strong Kitaev interactions for α -RuCl 3

  title={Effective model with strong Kitaev interactions for $\alpha$ -RuCl 3},

  journal={Physical Review B},
We use an exact numerical diagonalization method to calculate the dynamical spin structure factors of three ab initio models and one ab initio guided model for a honeycomb-lattice magnet $\ensuremath{\alpha}\text{\ensuremath{-}}{\mathrm{RuCl}}_{3}$. We also use thermal pure quantum states to calculate the temperature dependence of the heat capacity, the nearest-neighbor spin-spin correlation function, and the static spin structure factor. From the results obtained from these four effective… Expand

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.

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.
