The Net Advance of Physics.
There has been a great interest in magnetic field induced quantum spin liquids in Kitaev magnets after the discovery of neutron scattering continuum and half quantized thermal Hall conductivity in the material α-RuCl3. In this work, we provide a semiclassical analysis of the relevant theoretical models on large system sizes, and compare the results to previous studies on quantum models with. 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.

Neutron scattering in the proximate quantum spin liquid α-RuCl3.
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. We show how driving the strongly spin-orbit coupled proximal Kitaev magnet α-RuCl 3 with circularly-polarized light can give rise to a novel ligand-mediated magneto-electric effect that both photo-induces an effective magnetic field and dramatically alters the interplay of competing exchange interactions. We propose that tailored light pulses. Vacancy-Induced Low-Energy Density of States in the Kitaev Spin Liquid Abstract The Kitaev honeycomb model has attracted significant attention due to its exactly solvable spin-liquid ground state with fractionalized Majorana excitations and its possible materialization in magnetic Mott insulators with strong spin-orbit couplings.

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.
1T-TaS2 as a quantum spin liquid | PNAS.
In condensed matter physics, a quantum spin liquid is a phase of matter that can be formed by interacting quantum spins in certain magnetic materials. Quantum spin liquids (QSL) are generally characterized by their long-range quantum entanglement, fractionalized excitations, and absence of ordinary magnetic order. [1].

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.
