Theoretical concepts of spin-liquid phases are numer-ous and in most cases rather complex. However, from an experimental point of view, the identification of strong frustration effects in magnetic systems is straightforward and a much easier task. Systems with localized magnetic moments with spin S coupled by finite effective exchange. The controversy was sparked by a Nature paper [5] reported in 2018, led by a group from Kyoto University. In this paper, the authors measured the quantized thermal Hall effect in a magnetic field-induced quantum spin liquid phase and observed a quantized thermal Hall effect with half the value predicted from fermionic excitations, arguing for the existence of Majorana fermionic excitations. The study, "Oscillations of the thermal conductivity in the spin-liquid state of α-RuCl3," by Peter Czajka, Tong Gao, Max Hirschberger, Paula Lampen-Kelley, Arnab Banerjee, Jiaqiang Yan, David G. Mandrus, Stephen E. Nagler and N. P. Ong, was published in the journal Nature Physics online on May 13, 2021. DOI: 10.1038/s41567-021-01243-x.

Quantum spin liquid - Wikipedia.

We put forward proposals to explore the fractional liquid in α -RuCl 3 via thermodynamic and spin-polarized INS measurements. Remarkably, when the magnetic field is applied perpendicular to the. Model, a spin-1/2 model on a honeycomb lattice with bond-dependent spin interactions, has captured the interest of both the quantum computing and condensed matter com-munities [2,7,10-15,17-20]. The ground state of this model is an exactly solvable quantum spin liquid, and supports gapless excitation of Majorana fermions [2]. Unlike spin. 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 (QSL) in the ground state. Several complex iridium oxides, as well as α-RuCl3, are magnetic insulators with a honeycomb structure, and it was noticed that they accommodate essential ingredients of the.

2D proximate quantum spin liquid state in atomic-thin α-RuCl3 - IOPscience.

Having demystified the magnetic scattering and topological proximate QSL state in 2D α -RuCl 3, we focus on the temperature-driven evolution of magnetic continuum to inspect the layer dependent temperature that spin liquid correlations emerge. Figure 4 (a) shows the Raman intensity at low energy for 2 L, 3 L, 7 L and bulk. The layered honeycomb lattice material α-RuCl 3 has emerged as a prime candidate for displaying the Kitaev quantum spin liquid state, and as such has attracted much research interest. Here a new layered honeycomb lattice polymorph of RuI 3, a material that is strongly chemically and structurally related to α-RuCl 3 is described. The material is synthesized at moderately elevated pressures. Sub-gap optical response in the Kitaev spin-liquid candidate α-RuCl 3. J Phys Condens Matter. 2018 Nov 28;30(47):475604. doi: 10.1088/1361-648X/aae805.... One motivation is to unravel the microscopic nature of THz and spin-orbital excitations via a study of temperature and symmetry-induced changes. The optical studies are complemented by.

PDF Dynamical and thermal magnetic properties of the Kitaev spin liquid.

Combining inelastic neutron scattering(INS) study, we confirm the observed QSL state hosts energy-continuous spin excitation, which is highly related to the theoretical prediction of spinon. The third and fourth chapters of this thesis are dedicated to BaCo2(AsO4)2 and α-RuCl3, which are promising candidates for realizing the Kitaev model.

Evidence of a phonon Hall effect in the Kitaev spin liquid candidate α.

These combined experimental and computational data show that the Kitaev spin-liquid phase in α−RuCl3 strongly competes with the crystallization of spin singlets into a valence bond solid. Phys. Rev.

Kitaev quantum spin liquid response in RuCl3 | Neutron Scattering.

These exchange interactions were critical to fit the data which left an almost negligible isotropic Heisenberg exchange coupling in α-RuCl3. Quantum spin liquid. When you cool down a conventional magnet, the magnetic spins will eventually freeze into an ordered state, where each of the spins align with each other. The ORNL team has extensively studied the quantum spin liquid properties of ruthenium chloride. In a series of experiments extending over nearly three years, Czajka and Gao detected the temperature oscillations consistent with spinons with increasingly higher resolution, providing evidence that the electron is composed of two particles.

The Kitaev quantum spin liquid displays the fractionalization of quantum spins into Majorana fermions. The emergent Majorana edge current is predicted to manifest itself in the form of a finite thermal Hall effect, a feature commonly discussed in topological superconductors. Here we report on thermal Hall conductivity ${\ensuremath{\kappa}}_{xy}$ measurements in $\ensuremath{\alpha}\text.

Scattering Continuum and Possible Fractionalized Excitations in RuCl3.

Title: a-RuCl3 as a 2d crystalline acceptor: modulation doping, pn junctions, and the pursuit of Veselago's lens. Abstract: a-RuCl3 is a layered antiferromagnetic Mott insulator widely thought to host a quantum spin liquid state related to the Kitaev QSL. It can be exfoliated down to monolayer thicknesses and incorporated into van der Waals. The layered insulator α-RuCl 3 orders as a zigzag antiferromagnet at low temperature in zero magnetic field 4. The zigzag order is destroyed when a magnetic field is applied parallel to the zigzag axis. At moderate magnetic field strength, there is growing evidence that a quantum spin-liquid state exists. In the search for a spin liquid, the research team homed in on ruthenium trichloride.... More information: K. A. Modic et al, Scale-invariant magnetic anisotropy in RuCl3 at high magnetic fields.

Spin-phonon interactions in Quantum Spin Liquid Candidate α-RuCl3.

2021-12-31. Evidence for Magnetic Fractional Excitations in a Kitaev Quantum-Spin-Liquid Candidate α-RuCl3 Our group published a paper entitled "Evidence for Magnetic Fractional Excitations in a Kitaev Quantum-Spin-Liquid Candidate α-RuCl 3" in CPL as Express Letter [Chin. Phys. Lett. 39, 027501 (2022)]. α-RuCl 3 is by far the most promising candidate for Kitaev quantum-spin-liquid (QSL. A quantum spin liquid is an exotic quantum state of matter that does not exhibit any classical magnetic ordered ground state. The realization of such a state in actual materials is of significant importance as it would provide a path to protected states for quantum information applications and also to Majorana fermions - both areas of vigorous current activity and interest in condensed matter.

The spin probe technique is employed to study liquid-crystalline side chain polymers [1], oriented in a high frequency electric field [2]. Temperature and angular dependent electron spin resonance spectra are analyzed, using a comprehensive lineshape model [3]. Whether a quantum spin liquid phase exists just above that field is still an open question, but the reported observation of a quantized thermal Hall conductivity at H ∥ $ greater than $ 7 T by Kasahara and co-workers [Kasahara {}., Nature 559 , 227 (2018)] has been interpreted as evidence of itinerant Majorana fermions in the Kitaev quantum.
