Apparently, hydrostatic pressure is not the most promising approach to tune the honeycomb materials towards the desired Kitaev QSL, and it was concluded that, instead, strain would induce the QSL state Yadav et al. ( 2018), for example by chemical pressure Hermann et al. ( 2017 ); Simutis et al. ( 2018). The Kitaev model 1 is one of the greatest examples of two-dimensional (2D) solvable models of quantum spin liquids (QSLs) 2, 3, 4, especially in the perspective of spin-orbital-entangled physics 5.

Close to the Kitaev spin liquid regime [5]. The Kitaev spin model can be viewed as a Mott in-sulator at half lling, and one can ask about its phase diagram away from half lling. It is known that a Heisenberg antiferromagnet on the honeycomb lattice be-comes a d-wave superconductor upon doping [14]. Hence one may expect superconductivity in the.

Physics of emergence beyond Berezinskii-Kosterlitz-Thouless transition.

Abstract. Material realizations of the bond-dependent Kitaev interactions with S=1/2 local moments have vitalized the research in quantum spin liquids. Recently, it has been proposed that higher-spin analogs of the Kitaev interactions may also occur in a number of materials with strong spin-orbit coupling. In contrast to the celebrated S= 1/2.

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.

Relativistic Mott insulators known as ``Kitaev materials'' potentially realize spin liquids hosting non-Abelian anyons. Motivated by fault-tolerant quantum-computing applications in this setting, we introduce a dynamical anyon-generation protocol that exploits universal edge physics. The setup features holes in the spin liquid, which define energetically cheap locations for non-Abelian anyons. This exotic state of matter is called a quantum spin liquid. A goal of condensed matter physics is to discover new quantum phases formed by the ensemble of interacting spins and charges in solids.... I am going to talk about the rapid progress in the materialization Kitaev QSL as well as the hunting of Majorana fermions through the detection. The Kitaev spin liquid provides a rare example of well-established quantum spin liquids in more than one dimension.

The quantum spin liquid is a bizarre quantum phase of insulating magnets, firstly proposed by Philip Anderson in 1973, in which interacting magnetic moments remain disordered down to the lowest temperature under strong quantum fluctuations. They are characterized by topological entanglement and fractional excitations, whose possible application.

The Kitaev model is a fascinating example of an exactly solvable model displaying a spin-liquid ground state in two dimensions. However, deviations from the original Kitaev model are expected to appear in real materials. In this Letter, we investigate the fate of Kitaev's spin liquid in the presence of disorder---bond defects or vacancies---for an extended version of the model. Considering. 1. Introduction. Ionic liquids (ILs) have been a source of fascination for scientists and engineers for many decades. Since the discovery of air- and water-stable ILs by Wilkes in 1992 , research and development (R&D) of ILs has attracted overwhelming interest, and the number of publications concerning ILs has increased substantially.Owing to their peculiar and tunable properties compared to. 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.

Kitaev Quantum Spin Liquid: Concept and Materialization by Hidenori Takagi et al. [2019/03] Magnetic Susceptibility of Topological Semimetals by G.P. Mikitik and Yu. V. Sharlai [2019/03] Review of Borophene and its Potential Applications by Zhi-Qiang Wang et al. [2019/03]. Kitaev magnets have gained a huge amount of interest in recent years due to the possibility of such materials hosting a highly-entangled quantum spin liquid (QSL) ground state. Such materials are characterized by a honeycomb lattice structure and can be analytically solved by mapping the localized spins into itinerant and localized Majorana. Α-RuCl 3 is the most promising candidate for the long-sought materialization of the Kitaev model, where compasslike exchange interactions lead to a gapless spin liquid with emergent Majorana fermion excitations. Prerequisite for these expectations is that the symmetry-imposed noncubic crystal field is smaller compared to the spin-orbit coupling and does not perturb significantly the.

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.
