Temperature evolution of the phonon dynamics in the Kitaev spin liquid.

Abstract. The Kitaev model exhibits a canonical quantum spin liquid as a ground state and hosts two fractional quasiparticles, itinerant Majorana fermion and localized flux excitation. The former can carry heat and spin modulations in the quantum spin liquid, but the role of the latter remains unknown for the transport phenomena. Here, we focus.

Thus far, the coupling between graphene and ferromagneti. The Kitaev model and quantum spin liquid The Kitaev model consists of S= 1/2 spins on a honeycomb lattice, which are coupled to the three nearest neighbors by Ising interactions with bond-dependent easy-axes parallel to the x-, y- or z- axes21, as depicted in Fig. 1a. See Box 1for the corresponding Hamiltonian.

Scattering phenomena for spin transport in a Kitaev spin liquid.

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.

6 and provides new insight for the materialization of the Kitaev model. A quantum spin liquid QSL is a novel state of mat-ter where localized spins defy formation of long-range or-der due to frustrated interactions and/or quantum uc-tuations [13]. The concept has stimulated intense re-search ever since the original proposal of resonating va. Abstract A decade ago, Alexei Kitaev proposed an exactly solvable S = 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.

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 4d- and 5d-electron compounds including cations with the low-spin d 5 electron configuration, such as Ir 4 and Ru 3.

We show that the fractionalized spin excitations of the Kitaev spin liquid, the itinerant Majorana fermions, and static Z 2 fluxes have distinct effects on the phonon dynamics, which makes the phonon dynamics a promising tool for exploring the Kitaev spin liquid candidate materials. This Topical Review provides an overview over recent thermodynamic, infrared, and THz results on the proximate Kitaev spin-liquid. Quantum-spin liquids are exotic phases characterized by the absence of magnetic ordering even at the lowest temperatures and by the occurrence of fractionalized spin excitations..

Unveiling the S=3/2 Kitaev honeycomb spin liquids.

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.
