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

Recently, V-based kagome superconductors have emerged as a new research topic in condensed matter physics by intertwining superconductivity, charge density wave, and strong correlation. Here, the authors identify CsV 3 Sb 5 as a Dirac nodal-line semimetal by determining multiple Dirac nodal lines and loops close to the Fermi level with the help.

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.

PDF Perturbing the U(1) Dirac Spin Liquid State in Spin-1/2 kagome.

Recent work has begun to converge on the likely possibility that the antiferromagnetic Heisenberg model on the kagome lattice, or kagome Heisenberg antiferromagnet (KHAF), is a spin liquid in the ground state [ 4 - 10 ]. While it might be natural to think that there is but one way to not be ordered—that is, a single spin-liquid phase.

The kagome Heisenberg antiferromagnet is a leading candidate in the search for a spin system with a quantum spin-liquid ground state. The nature of its ground state remains a matter of active debate. We conducted oxygen-17 single-crystal nuclear magnetic resonance (NMR) measurements of the spin-1/2 kagome lattice in herbertsmithite [ZnCu 3 (OH.

Entanglement signatures of emergent Dirac fermions: Kagome spin liquid.

. Plateaus can be observed in the zero-temperature magnetization curve of quantum spin systems at rational values of the magnetization. In one dimension, the appearance of a plateau is controlled by a quantization condition for the magnetization which involves the length of the local spin and the volume of a translational unit cell of the ground.

Trihexagonal tiling - Wikipedia.

Spin ices are geometrically frustrated magnetic systems. While frustration is usually associated with triangular or tetrahedral arrangements of magnetic moments coupled via antiferromagnetic exchange interactions, as in Anderson's Ising model, spin ices are frustrated ferromagnets. It is the very strong local magnetic anisotropy from the. Abstract: We construct a lattice model of topological order (kagome quantum spin liquids) and solve it with unbiased quantum Monte Carlo simulations. A three-stage anyon condensation with two transitions from a $\mathbb Z_2\boxtimes\mathbb Z_2$ topological order to a $\mathbb Z_2$ topological order and eventually to a trivial symmetric phase is revealed. Measurement. When no external field is applied, the antiferromagnetic structure corresponds to a vanishing total magnetization. In an external magnetic field, a kind of ferrimagnetic behavior may be displayed in the antiferromagnetic phase, with the absolute value of one of the sublattice magnetizations differing from that of the other sublattice, resulting in a nonzero net magnetization.

Nellutla, J. van Tol, et al. Dzyaloshinsky-Moriya Anisotropy in the Spin-1/2 kagome Compound ZnCu 3 (OH) 6 Cl 2. 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. 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 successful Li.
