Identification of strongly correlated spin liquid in herbertsmithite.

The apparent simplicity of Herbertsmithite belies the complexity of the spin liquid state that it apparently supports, Broholm says, which could make it useful someday. "The structural simplicity of Herbertsmithite is valuable if we are to put the quantum spin liquid to use—as proposed for information processing, for example," he says. One favorable situation for spins to enter the long-sought quantum spin liquid (QSL) state is when they sit on a kagome lattice. No consensus has been reached in theory regarding the true ground state of this promising platform. The experimental efforts, relying mostly on one archetypal material ZnCu 3 (OH) 6 Cl 2, have also led to diverse possibilities. The theoretical possibility of a "quantum spin liquid," for which there is no breaking of spin rotational symmetry, remained an intriguing possibility(5).In1973PhilipAndersonproposed that the ground state of a simple quantum mechanical model—the spin-½ antiferromag-netic near-neighborHeisenbergmodel (6)on atriangularlattice.

A New State Of Matter: Quantum Spin Liquids Explained.

Quantum spin liquids form a novel class of matter where, despite the existence of strong exchange interactions, spins do not order down to the lowest measured temperature. Typically, these occur in lattices that act to frustrate the appearance of magnetism. In two dimensions, the classic example is the kagome lattice composed of corner sharing triangles.. A liquid-like state called a quantum spin liquid (QSL). The herbertsmithite ZnCu 3 (OH) 6 Cl 2 has been ex posed as a S = 1 / 2 kagome antiferromagnet, and recent ex. It has been suggested that the nearest-neighbor antiferromagnetic Heisenberg model on the Kagome lattice may be a good starting point for understanding the spin-liquid behavior discovered in herbertsmithite. In this work, we investigate possible quantum spin liquid phases in the presence of spin-rotation symmetry-breaking perturbations such as Dzyaloshinskii-Moriya and Ising interactions, as.

. The frustrated magnet (insulator) herbertsmithite ZnCu 3 (OH) 6 Cl 2 is one of the best candidates for identification as a material that hosts a quantum spin liquid (QSL), thereby determining the nature of its thermodynamic, relaxation, and transport properties. The insulating nature of ZnCu 3 (OH) 6 Cl 2 has been established: There is a 3.3 eV charge gap (see e.g., [1,2]). An exotic quantum spin liquid (QSL) is formed with such hypothetic particles as fermionic spinons carrying spin 1/2 and no charge. Here we calculate its thermodynamic and relaxation properties.... This demonstrates that the spin liquid of herbertsmithite is close to QCP and behaves like the HF liquid of YbRh 2 Si 2 in strong magnetic fields.

We report 17O NMR measurements in the S=1/2 Cu2+ kagome antiferromagnet Herbertsmithite ZnCu3(OH)6Cl2 down to 45mK in magnetic fields ranging from 2T to 12T. While Herbertsmithite displays a gapless spin-liquid behavior in zero field, we uncover an instability toward a spin-solid phase at sub-kelvin temperature induced by an applied magnetic field. The latter phase shows largely suppressed.

For Newly Discovered 'Quantum Spin Liquid', the Beauty Is in.

Since the proposal by Anderson of the resonating valence bond state, 1) the quantum spin-liquid (QSL) state possibly realized in certain $S = 1/2$ frustrated magnets has attracted interest of researchers. 2) After a long experimental quest, several candidate materials were recently reported in geometrically frustrated magnets, including both the triangular-lattice and the kagome-lattice. Called a Dirac spin liquid, is special, and is a candidate ground state for several sim-ple models as well as several materials (such as Herbertsmithite and Ba 8CoNb 6O 24). A Dirac spin liquid is described in terms of spin-half fermions with a massless Dirac dispersion, coupled to an emergent photon eld. This gauge theory is just like the. Quantum spin liquid candidate becomes a superconductor under pressure. According to the researchers, who present their results in Science, such defects may in fact prove crucial to the low-temperature magnetic properties of all quantum spin systems that lack magnetic order.Indeed, there are now only a few QSL candidates in which a spin gap has not been proven beyond any doubt, they explain.

Quantum Spin-Liquid Behavior in the Spin-1/2 Random-Bond Heisenberg.

When the randomness exceeds a critical value, the ground state of the model exhibits a transition within the non-magnetic state into the randomness-relevant gapless spin-liquid state. Implications to the S=1/2 kagome-lattice antiferromagnet herbertsmithite is discussed. Quantum spin liquid (QSL) represents a new state of matter characterized by long-range entanglement, beyond the conventional symmetry-breaking paradigm [1]. Realizing QSL in real-world materials has been a long-sought goal for decades [2-4]. The most promising candidate so far is herbertsmithite Cu 3Zn(OH) 6Cl 2, which realizes the S = 1/2. The conditions for a quantum spin liquid to arise are often found in nature, like in the magnetic layers of copper ions of the mineral Herbertsmithite. But synthetically creating this state of.
