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 [1{3]. The concept has stimulated intense re-search ever since the original proposal of resonating va. Nov 18, 2019 · Kitaev spin liquid. One of the materials, where spin liquid can be realized, is so-called Kitaev materials. They can be loosely defined as Mott insulators that exhibit bond-directional exchange interactions and are thought to have unconventional forms of magnetism like spin liquids.

Nagler Physics 2019 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… 18 PDF.
Neutron scattering in the proximate quantum spin liquid α-RuCl3.
We show how driving the strongly spin-orbit coupled proximal Kitaev magnet α-RuCl 3 with circularly-polarized light can give rise to a novel ligand-mediated magneto-electric effect that both photo-induces an effective magnetic field and dramatically alters the interplay of competing exchange interactions. We propose that tailored light pulses. Kitaev Quantum Spin Liquids - Concept and Materialization Feb. 25: Kitaev Spin Liquids II Lecture Slides... Effect in a Kitaev Spin Liquid. Now we have strong evidence to support the spin liquid state in at least two cases: the organic compounds close the the Mott transition and in certain Kagome lattices. In light of our recent experience, we can say that existing data are pointing strongly toward a quantum spin liquid state for the 1T-TaS 2 Mott insulator. Due to the rather low.

In condensed matter physics, a quantum spin liquid is a phase of matter that can be formed by interacting quantum spins in certain magnetic materials. Quantum spin liquids (QSL) are generally characterized by their long-range quantum entanglement, fractionalized excitations, and absence of ordinary magnetic order. [1].

Alexei Kitaev - Wikipedia.
The most prominent examples of quantum-spin liquids (QSLs), are the resonating valence-bond state introduced by Anderson and the Kitaev-type spin liquid on a honeycomb lattice. Reviews on frustrated magnets or spin liquids can be found in references [ 3 , 4 ].

Magnetic Field Induced Competing Phases in Spin-Orbital Entangled.
The combination of two-dimensional (2D) materials into vertical heterostructures has emerged as a promising path to designer quantum materials with exotic properties. Here, we extend this concept from inorganic 2D materials to 2D metal-organic frameworks (MOFs) that offer additional flexibility in realizing designer heterostructures. We successfully fabricate a monolayer 2D Cu.

Vacancy-Induced Low-Energy Density of States in the Kitaev Spin Liquid Abstract 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. Jun 09, 2017 · The Kitaev quantum spin liquid (KQSL) is an exotic emergent state of matter exhibiting Majorana fermion and gauge flux excitations. The magnetic insulator α-RuCl 3 is thought to realize a proximate KQSL. We used neutron scattering on single crystals of α-RuCl 3 to reconstruct dynamical correlations in energy-momentum space. 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.

Jan 17, 2020 · An overview of an exotic type of liquid. Materials with interacting quantum spins that nevertheless do not order magnetically down to the lowest temperatures are candidates for a materials class called quantum spin liquids (QSLs). QSLs are characterized by long-range quantum entanglement and are tricky to study theoretically; an even more.

Phys. (2019). 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.
