Concept and realization of Kitaev quantum spin liquids. Nearly two decades ago, Alexei Kitaev proposed a model for spin- particles with bond-directional interactions on a two-dimensional honeycomb lattice which had the potential. The Kitaev model and quantum spin liquid The Kitaev model 21 consists of S = 1/2 spins on a honeycomb lattice, with nearest-neighbour Ising. It was soon recognized that a family of complex iridium oxides, as well as ruthenium chloride, with honeycomb structure are magnetic insulators and accommodate essential ingredients of the Kitaev model, due to the interplay of electron correlation and spin-orbit coupling.
Designing Kitaev Spin Liquids in Metal-Organic Frameworks.
The excitation spectrum of -RuCl3 is proposed as a prime candidate for fractionalized Kitaev physics, and dynamical response measurements above interlayer energy scales are naturally accounted for in terms of deconfinement physics expected for QSLs. Quantum spin liquids (QSLs) are topological states of matter exhibiting remarkable properties such as the capacity to protect quantum. 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. Traditionally, frustrated magnets have been extensively investigated for so-called quantum spin liquid (QSL) phases. This phase has been expected to exhibit novel features. One example is the fractionalization of an electron into charge and spin in the absence of any long-range order [ 2 , 6 ].
Theoretical and experimental developments in quantum spin liquid in.
Abstract. Kitaevs honeycomb lattice spin model is a remarkable exactly solvable model, which has a particular type of spin liquid (Kitaev spin liquid) as the ground state. Although its possible realization in iridates and RuCl3 has been vigorously discussed recently, these materials have substantial non-Kitaev direct exchange. The Kitaev quantum spin liquid epitomizes an entangled topological state, for which two flavors of fractionalized low-energy excitations are predicted: the itinerant Majorana fermion and the Z[2] gauge flux. It was proposed recently that fingerprints. The realization of Kitaev's honeycomb magnetic model in real materials has become one of the most pursued topics in condensed matter physics and materials science. If found, it is expected to host exotic quantum phases of matter and offers potential realizations of fault-tolerant quantum computation.

May 04, 2022 Single-electron pumps realized by quantum dots with tunable barriers are the most promising candidates for the direct realization of a quantized current. The current understanding of residual errors is based on the evaluation of unwanted back-tunneling of electrons to the source. 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 (QSL) in the ground state. Several complex iridium oxides, as well as -RuCl3, are magnetic insulators with a honeycomb structure, and it was noticed that they accommodate. We study the spin transport through the quantum spin liquid (QSL) by investigating the real-time and real-space dynamics of the Kitaev spin system with zigzag edges using the time-dependent Majorana mean-field theory. After the magnetic-field pulse is introduced to one of the edges, spin moments are excited in the opposite edge region although spin moments are never induced in the Kitaev QSL.

Ultracold atoms and molecules trapped in optical lattices are expected to serve as simulators of strongly correlated systems and topological states of matter. A fascinating example is to realize the Kitaev quantum spin liquid by using ultracold polar molecules. However, although experimental implementation of the Kitaev-type interaction was proposed, the stability of the Kitaev quantum spin.

An exotic quantum state in condensed matter physics is the J eff = 1 2 state in honeycomb iridate materials that leads to the Kitaev exchange interaction (16).The J eff = 1 2 state is a product of strong spin-orbit coupling (SOC) in heavy Ir 4+ ions that splits the t 2g manifold into a J eff = 3 2 quartet and a J eff = 1 2 doublet.

Majorana-Mediated Spin Transport in Kitaev Quantum Spin Liquids.
Indeed, such state exists and is called quantum spin liquid (QSL). The main difference between QSL and VBS is that former state is characterized by long-range quantum entanglement. This implies that the valence bonds can be of arbitrary range, see Fig. 4. Three-dimensional Kitaev models -- generalizations of the well known exactly solvable Kitaev honeycomb model -- exhibit a rich variety of quantum spin liquid phases. Their fractionalized excitations are Majorana fermions that may form topological band structures. These can be enriched by lattice symmetries, as shown in the present work. In particular, the authors propose two new instances of. Feb 15, 2019 Furthermore, exotic spin textures and topologically protected spin configurations (e.g., magnetic skyrmions) in 2D magnets or heterostructures remain open to explore by rationally weighing the material constituents, crystal symmetry, spin-orbit coupling, Rashba effect, and spin (re-)orientations. New quantum phases and quasiparticles could be.
