This Kitaev quantum spin liquid supports magnetic excitations equivalent to Majorana fermionsparticles that are unusual in that they are their own antiparticles. The presence of Majorana fermions is of great interest because of their potential use as the basis for a qubit, the essential building block of quantum computers. Familiar. The quantum spin liquid QSL is an exotic state of matter with long-range coherence but with no spontaneous breaking of translational or spin-rotational symmetry down to zero temperature [1]. Such a state in two or higher dimensions has implications for phenomena ranging from high-temperature superconductivity [2] to quantum com.
New evidence for electron#39;s dual nature found in a quantum.
May 13, 2021 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. According to literature, RuCl3 may be the realization of a new theoretical phase of matter called a spin liquid. This materials seems to fit the profile and has been investigated using a Kitaev model. In this study, we re-examine the data for RuCl3 using a standard Heisenberg spin-spin exchange model with easy axis anisotropy.

The Kitaev quantum spin liquid KQSL is an exotic emergent state of matter exhibiting Majorana Fermion and gauge flux excitations. The magnetic insulator -RuCl3 is thought to realize a proximate KQSL.

Plumb et al. [1] found that spin-orbit coupling in this material is substantial, leading to a j eff = 1 2 state description of the Ru3 valence electrons. Since this material is built up with edge-sharing RuCl... Kitaev interaction [2,3], making -RuCl 3 a material of great interest in the ongoing search for a Kitaev spin-liquid ground.
New evidence for electrons dual nature found in a quantum.
Here we report the first Raman scattering study on phonon-magnetic scattering coupling, proximate quantum spin liquid ground state and collective fractionalized excitations in exfoliated -RuCl3 atomic layers. Our results uncover that 2D -RuCl3 could harbour the unusual magnetic continuum, serving as a hallmark of the 2D proximate quantum.... In RuCl3, an external magnetic field applied within the honeycomb plane can induce a transition from a magnetically ordered state to a disordered state that is potentially related to the Kitaev quantum spin liquid. In zero field, single crystals with minimal stacking faults display a low-temperature state with in-plane zigzag.
Proximate Kitaev Quantum Spin Liquid Behavior in -RuCl3.
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 -RuCl3, are magnetic insulators with a honeycomb structure, and it was noticed that they accommodate essential ingredients of 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.

Evidence of a Phonon Hall Effect in the Kitaev Spin Liquid.
These exchange interactions were critical to fit the data which left an almost negligible isotropic Heisenberg exchange coupling in -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 layered honeycomb lattice material -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 -RuCl 3 is described.

How many magnetic-field induced phase transitions in RuCl3?.
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.
