A two-dimensional spin liquid in quantum kagome ice.

This information is critical for comparatively evaluating the leading theories on the ground state of the S = 1/2 KHA: a gapped spin liquid, gapless spin liquid, or valence-bond solid ( 1, 2, 9 – 14) Fig. 1 Kagome lattice and the structure of ZnCu 3 (OH) 6 Cl 2. ( A) A kagome lattice formed by corner-shared triangles. 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.

Gapless Spin-Liquid Ground State in the S=1 2 Kagome.

The authors review recent density-matrix renormalization group studies of lightly doped quantum spin liquids (QSLs) on the kagome lattice. While a number of distinct conducting phases, including high temperature superconductivity, have been theoretically anticipated, a tendency toward fractionalized insulating charge-density-wave (CDW) states is instead found. A quantum spin liquid (QSL) is an exotic quantum ground state that does not break conventional symmetries and where the spins in the system remain dynamic down to zero temperature.... (0 ≤ x ≤ 1), where perfect kagome layers of spin-1/2 Cu 2+ are separated from each other by the non-magnetic Zn layers. Since then, extensive. A numerical analysis suggests that the elusive ground state of the antiferromagnetic Heisenberg model for the kagome lattice is a gapless spin liquid. APS/ Alan Stonebraker. Figure 1:Liao and colleagues [ 1] performed a numerical simulation on an infinite kagome lattice (green). As they turn up the value of a parameter D (shown by the meter) in.

Electron Doping of Proposed Kagome Quantum Spin Liquid Produces.

This frustrated spin system has long been thought to be an ideal candidate for a simple, physically realistic model that shows a spin-liquid ground state (1–3). A spin liquid is a magnetic system that has “melted” in its ground state because of quantum fluctuations, so it has no spontaneously broken symmetries. A key problem in searching for spin liquids in two.

Rev. Mod. Phys. 89, 025003 (2017) - Quantum spin liquid states.

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. In conclusion, we have successfully synthesized a new kagome compound Cu 3 Zn(OH) 6 FBr and its quantum spin liquid ground state is verified in our thermodynamical measurements. Our 19 F NMR data reveals a gapped spin-liquid ground state for Cu 3 Zn(OH) 6 FBr, similar to previous 17 O NMR results on herbertsmithite. Most importantly, we provide.

Kapellasite: A Kagome Quantum Spin Liquid with Competing Interactions.

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.. The quantum spin liquid state was first proposed by physicist Phil. Abstract. Herbertsmithite, ZnCu 3 (OH) 6 Cl 2, is a two-dimensional kagome lattice realization of a spin liquid, with evidence for fractionalized excitations and a gapped ground state.Such a quantum spin liquid has been proposed to underlie high-temperature superconductivity and is predicted to produce a wealth of new states, including a Dirac metal at 1/3 electron doping.

The Search for the Quantum Spin Liquid in Kagome Antiferromagnets.

Roychowdhury et al. studied the transition from the even Z 2 spin liquid into the nematic phase. The visons in this Z 2 spin liquid have an energy dispersion with minima at M 1 = (π / 2, − π / (2 3)) = b 1 / 2, M 2 = (0, π / 3) = b 2 / 2 , and their condensation leads to the nematic ordering for which the dominant wavevectors are b 1, b 2.

New State of Matter Observed through Entangled Particles.

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 recent experiment on herbertsmithite with. Magnetic susceptibility, NMR, muon spin relaxation, and inelastic neutron scattering measurements show that kapellasite, Cu 3 Zn (OH) 6 Cl 2, 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 down to 20 mK. So far, the only theoretical model for a spin liquid state on the kagome lattice which naturally gives rise to a flat excitation band at low energies consists of the Z 2 spin liquids 2,3,4.

Studied the Li intercalation doping eﬀects of the two kagome spin liquid compounds. In the Li-doped herbertsmithite, it was speculated that Li is located in the Cl-(OH) 3 tetrahedron hole (T-site).28 Based on this structure, singlet trapping and electron localization were proposed to explain the insulating behavior.

Gapless spin liquid in a square-kagome lattice.

The ground state of the spin−1/2 kagome antiferromagnet remains uncertain despite decades of active research. Here we step aside from this debated question to address the ground-state nature of a related, and potentially just as rich, system made of corner-sharing triangles: the square-kagome lattice (SKL). Our work is motivated by the recent synthesis of a distorted SKL compound mentioned.
