Concept and realization of Kitaev quantum spin liquids.

Abstract. The Kitaev model is an exactly solvable S = 1/2 spin model on a 2D honeycomb lattice, in which the spins fractionalize into Majorana fermions and form a topological quantum spin liquid. Quantum spin liquids realize massive entanglement and fractional quasiparticles from localized spins, proposed as an avenue for quantum science and technology. In particular, topological quantum computations are suggested in the non-abelian phase of Kitaev.

May 31, 2019 · The Kitaev model with an applied magnetic field in the H ∥ [111] direction shows two transitions: from a nonabelian gapped quantum spin liquid (QSL) to a gapless QSL at H c 1 ≃ 0.2 K and a second transition at a higher field H c 2 ≃ 0.35 K to a gapped partially polarized phase, where K is the strength of the Kitaev exchange interaction.

In this master thesis, we investigate quantum disordered spin liquid ground states of the Heisenberg-Kitaev model on the triangular lattice using Schwinger-boson mean- eld theory. Our goal is to identify and characterize potential gapped spin liquid ground states. After reviewing known results of Heisenberg-Kitaev model, projective. Based on this mechanism, there has been a fierce race for the materialization of the Kitaev spin liquid over the last decade, but the candidates have been still limited mostly to 4 d- and 5 d-electron compounds including cations with the low-spin.

The Net Advance of Physics.

Now we have strong evidence to support the spin liquid state in at least two cases: the organic compounds close the the Mott transition and in certain Kagome lattices. In light of our recent experience, we can say that existing data are pointing strongly toward a quantum spin liquid state for the 1T-TaS 2 Mott insulator. Due to the rather low.

Feb 27, 2020 · Here, via extensive first-principles-based simulations, we report the investigation of the Kitaev physics and possible Kitaev QSL state in epitaxially strained Cr-based monolayers, such as CrSiTe 3, that rather possess a S = 3 / 2 spin value. Our study thus extends the playground of Kitaev physics and QSLs to 3 d transition metal compounds. [1903.07721] Do tensor renormalization group methods work for frustrated spin systems?

Jun 09, 2017 · The Kitaev quantum spin liquid (KQSL) is an exotic emergent state of matter exhibiting Majorana fermion and gauge flux excitations. The magnetic insulator α-RuCl 3 is thought to realize a proximate KQSL. We used neutron scattering on single crystals of α-RuCl 3 to reconstruct dynamical correlations in energy-momentum space.

PDF - Kitaev quantum spin liquids (QSLs) are exotic states of matter that are predicted to host Majorana fermions and gauge flux excitations. However, so far all known Kitaev QSL candidates are known to have appreciable non-Kitaev interactions that pushes these systems far from the QSL regime. Using time-domain terahertz spectroscopy (TDTS) we show that the honeycomb cobalt-based Kitaev QSL.
