A). Figure 2: Infidelity (a) and energy distance (b) between the variational and true Kitaev model GS, shown as a function of d for the final epoch out of 500. We consider J =−1, h= 0, and four system sizes N ={8,12,18,24}. (c) Infidelity at different epochs and N. d is chosen as the closest integer to N /6. A quantum spin liquid, or QSL, is a special kind of magnetic state that can only occur in particular types of materials. By observing changes in the quantum sound waves (phonons) traveling within a tiny sample of RuCl 3, the scientists were able to identify two distinct quantum excitations characteristic of a QSL. The phonons were detected and measured during inelastic x-ray scattering (IXS) experiments carried out using the U.S. Department of Energy's Advanced Photon Source (APS).

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.

Abstract. Elementary excitations in entangled states such as quantum spin liquids may exhibit exotic statistics different from those obeyed by fundamental bosons and fermions. Non-Abelian anyons exist in a Kitaev spin liquid-the ground state of an exactly solvable model.

Majorana fermions in the Kitaev quantum spin system α-RuCl 3.

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.

Concept and realization of kitaev quantum spin liquids.

Kitaev quantum spin liquid - concept and materialization Hidenori Takagi1,2,3*, Tomohiro Takayama1,2*, George Jackeli1,2* and Giniyat Khaliullin1* 1. Kitaev spin liquids on honeycomb lattice are based on bond-dependent ferromagnetic interactions, distinct from geometrically frustrated antiferromagnet, in that the presence of spin liquid state was theoretically and rigorously proven, and may bring a new paradigm in the science of quantum spin liquid [10]. α-A 2 IrO 3 (A = Li, Na) was. 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. This initiated a race to materialize the Kitaev QSL and to capture the signature of Majorana fermions. In this.

Apr 04, 2016 · The Kitaev model consists of a set of spin-1/2 moments { Si } arrayed on a honeycomb lattice. The Kitaev couplings, of strength K in equation (1), are highly anisotropic with a different spin.

Quantum Spin Liquids - Journal of Physics: Condensed Matter.

Kitaev model is a quantum spin liquid with a Z 2 gauge structure. We are also able to put an upper bound on the excitation gap. The magnetic ﬁeld responses for the FM and AFM models are similar to those of the S = 1/2 counterparts. In particular, in the AFM S = 1 model, a gapless quantum spin-liquid state emerges in an. 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.

Physical Review Research - Accepted Paper: Light-induced.

Excitations in the field-induced quantum spin liquid state of α-RuCl3. A. Banerjee, P. Lampen-Kelley, +14 authors. S. Nagler. Physics. 2017. The celebrated Kitaev quantum spin liquid (QSL) is the paradigmatic example of a topological magnet with emergent excitations in the form of Majorana Fermions and gauge fluxes. At this point, the key to a quantum spin liquid appears to be merely a matter of a little fine tuning. The β-Li 2 IrO 3 compound structure (Fig. 2) is the simplest of the three-dimensional Kitaev systems. Due to its crystal symmetry, one of the Kitaev interactions favors b-axis spin coupling, likely the reason that the system's ground state.

A new state of matter: Quantum spin liquids explained - P.

A quantum spin liquid (QSL) is an exotic phase of matter in which the magnetic moments, or spins, remain jumbled even at zero temperature. Researchers are interested in how QSLs respond to disorder in the form of vacancies, impurities, and atomic-bond randomness, all of which are inevitable in real materials. Kitaev quantum spin liquid - concept and materialization. A decade ago, Alexei Kitaev proposed an exactly solvable = 1/2 model on a two-dimensional honeycomb lattice, where the spins fractionalize into Majorana fermions and form a topological quantum spin liquid (QSL) in the ground state. It was soon recognized that a family of complex iridium.

An ultrafast 6- fs measurement of charge dynamics and a quantum mechanical analysis clarify the mechanism, i.e., the orbital moment emerges from a spiral and coherent charge motion between different t2g orbitals (dyz-dxz-dxy) of Ru3+ ions, where this interorbital charge hopping through the d-p hybridization governs the stability of the Kitaev.
