Electron doping a kagome spin liquid (Journal Article) | DOE PAGES.

Kagome lattices are one of the simplest structures believed to possess a spin liquid state, and the new findings, revealed by neutron scattering, indeed show striking evidence for a fundamental. Herbertsmithite and Zn-doped barlowite are two compounds for experimental realization of two-dimensional kagome spin liquids. Theoretically, it has been proposed that charge doping a quantum spin liquid gives rise to exotic metallic states, such as high-temperature superconductivity. However, one re. Among them, the Kagome antiferromagnet (KAFM) herbertsmithite (8–11) is one of the most promising spin liquid candidates. A possible magnetic order of this material has been excluded down to temperatures a few orders of magnitude below the coupling energy scale ( 9 , 10 ).

Next ». First theorized in 1973 by physicist Philip W. Anderson, quantum spin liquids are exotic phases of matter with topological order. They feature long-range quantum entanglement that can.

Kagome Chiral Spin Liquid as a Gauged U(1) Symmetry Protected.

With a corner-shared triangle structure (Fig.1A) is crucial for the search for a quantum spin liquid ground state (1,2). Spin-liquids consist of entangled pairs of spin-singlets, and do not undergo a magnetic phase transition. The successful synthesis of the structurally ideal kagome lattice of Cu2+ ions (spin S=1/2) in herbertsmithite ZnCu 3. We argue that a relatively simple model containing only SU(2)-invariant chiral three-spin interactions on a Kagome lattice of S = 1/2 spins can give rise to both a gapped and a gapless quantum spin liquid. Our arguments are rooted in a formulation in terms of network models of edge states and are backed up by a careful numerical analysis. Polymorphs of ZnCu 3 (OH) 6 Cl 2 (herbertsmithite and kapellasite) and related cuprates MCu 3 (OH) 6 Cl 2 (M = Mg 2+, Ca 2+, Cd 2+, Co 2+, Fe 2+, Mn 2+ and Ni 2+) with antiferromagnetic Kagomé lattices have attracted attention for intensively investigating the quantum spin liquid (QSL) materials.However, mixing between magnetic (Cu 2+) and diamagnetic divalent ions (Zn 2+, Mg 2+, etc.) is.

The properties of ground state of spin-\frac{1}{2}12 kagome antiferromagnetic Heisenberg (KAFH) model have attracted considerable interest in the past few decades, and recent numerical simulations reported a spin liquid phase. The nature of the spin liquid phase remains unclear. For instance, the interplay between symmetries and Z_2Z2 topological order leads to different types of Z_2Z2 spin.

Realizing kagome spin ice in a frustrated intermetallic compound.

Fig 2. Physics of creating spin-pairs in a frustrated lattice. Ground state atoms (green dots) are arranged in an edge-Kagome lattice, where each atom sits in the middle of the edges of a Kagome lattice.Once a coherent laser field drives all atoms towards their Rydberg state, Rydberg-Rydberg interactions start playing a role, which prevents neighboring atoms to be both in the Rydberg states.

For newly discovered 'quantum spin liquid', the beauty is in its simplicity.

Magnetic susceptibility, NMR, muon spin relaxation, and inelastic neutron scattering measurements show that kapellasite, Cu3Zn(OH)6Cl2, a geometrically frustrated spin-1/2 kagome antiferromagnet polymorphic with herbertsmithite, is a gapless spin liquid showing unusual dynamic short-range correlations of noncoplanar cuboc2 type which persist.

Employing large-scale quantum Monte Carlo simulations, we study the extended X X Z model on the kagome lattice. A Z 2 quantum spin liquid phase with effective even Ising gauge field structure emerges from the delicate balance among three symmetry-breaking phases including stripe solid, staggered solid, and ferromagnet.

Closing in on the Kagome Magnet Published 29 March 2017. A numerical analysis suggests that the elusive ground state of the antiferromagnetic Heisenberg model for the kagome lattice is a gapless spin liquid. Al.8has provided striking evidence for a spin liquid ground state for the S= 1=2 Heisenberg antiferromagnet on the kagome lattice. Yan et al. found a gap to all excitations, and it is plausible that their ground state realizes a Z 2spin liquid.9{16 The results of Yan et al. also indicate the presence of proximate valence bond solid.

In a famous paper in 1987, Kalmeyer and Laughlin 4 hypothesized a scenario where a chiral topological spin liquid (CSL) is formed. In this elusive phase of matter, the spins form a collective state. Seen in triangular and kagome antiferromagnets reported to have a spin-liquid ground state.
