For Newly Discovered 'Quantum Spin Liquid', the Beauty Is in Its.
. Herbertsmithite is an experimental realization of the so-called quantum kagome antiferromagnet, a system that is predicted to host a spin liquid state down to zero temperature. Detailed NMR. The term 'quantum spin liquid' (QSL) originates from Anderson's 1973 paper describing a 'quantum liquid' ground state of an antiferromagnet , which he called a 'resonating valence bond' (RVB) state. Given that there has been more than four decades of development since then, we begin with a brief guide to key historical developments.
Quantum spin liquids: a review - IOPscience.
The conditions required for a quantum spin liquid to form are often found in nature. The most famous example is the copper-based mineral Herbertsmithite, for which there is significant evidence to. 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.
Colloquium: Herbertsmithite and the search for the quantum spin liquid.
A Majorana fermion is a particle which equals its own antiparticle, and can emerge as a quasiparticle in certain superconductors, or in a quantum spin liquid. [14] Magnetic monopoles arise in condensed matter systems such as spin ice and carry an effective magnetic charge as well as being endowed with other typical quasiparticle properties such.

New measurements of herbertsmithite isolate the role of spins on the vertices of its triangular kagome atomic lattice to its quantum spin-liquid ground state. Show Abstract Condensed Matter Physics.
Revealing quantum spin liquid in the herbertsmithite $\rm ZnCu_{3}(OH.
"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. "Complex chemistry usually brings disorder, but this material is relatively simple, so it realizes the quantum spin liquid with higher fidelity."..

Herbertsmithite.
Neutron scattering measurements on single-crystal samples of the mineral herbertsmithite, which is a spin-1/2 kagome-lattice antiferromagnet, provide evidence of fractionalized spin excitations at. The HKA spin liquid evolves into a Kalmeyer-Laughlin chiral spin liquid [8, 9], a magnetic analogue of the topo-logical order in the fractional quantum Hall e ect [13], and connected to the physics of the Kapellasite material [10, 11]. Perturbations beyond the HKA are thus a fertile ground for exotic quantum phenomena. By contrast, the quantum spin liquid refers to ground states in which the prototypical wave function has long-range quantum entanglement between local degrees of freedom. Under smooth deformations, such a wave function cannot be reduced to a product state wave function in real space. Such long-range quantum entanglement should be.

. The spin-1/2 kagom e Heisenberg antiferromagnet is generally accepted as one of the most promis-ing two-dimensional models to realize a quantum spin liquid state. Previous experimental e orts were almost exclusively on only one archetypal material, the herbertsmithite ZnCu 3(OH) 6Cl 2, which..
Fractionalized excitations in the spin-liquid state of a kagome-lattice.
We demonstrate that herbertsmithite's low-temperature properties are defined by a strongly correlated quantum spin liquid made with hypothetic particles such as fermionic spinons that carry spin 1/2 and no charge.

To analyze recent measurements of the herbertsmithite optical conductivity at different temperatures, we employ a model of a strongly correlated quantum spin liquid located near the fermion condensation phase transition. Our theoretical analysis of the optical conductivity allows us to reveal the physical mechanism of its temperature dependence.. 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]).
Trihexagonal tiling - Wikipedia.
Transition-metal based kagome materials, hosting corner-sharing triangles, offer an exciting platform to explore intriguing correlated 1,2,3 and topological phenomena 4,5,6, including quantum spin. Heat Transport in Herbertsmithite: Can a Quantum Spin Liquid Survive Disorder? Arguably the most 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.

Dicted novel class of disordered quantum phases general-izing the Dirac spin liquid and decon ned quantum crit-ical point [65,66]. The simplest never-yet-observed ex-ample of a Stiefel liquid should occur in proximity to the non-coplanar tetrahedral magnetic order [65], while an-other Stiefel liquid could arise near a nematic phase [66]. We analyze recent heat capacity measurements in herbertsmithite ZnCu 3 (OH) 6 Cl 2 single crystal samples subjected to strong magnetic fields. We show that the temperature dependence of specific heat C mag formed by quantum spin liquid at different magnetic fields B resembles the electronic heat capacity C el of the HF metal YbRh 2 Si 2.We demonstrate that the spinon effective mass M mag.
A nematic spin liquid phase with incipient ferroelectricity in.
Scientific Achievement Motivated by second harmonic generation data, we have studied possible crystal distortions in herbertsmithite and related copper materials. Significance and Impact The resulting valence bond patterns define a nematic spin liquid that breaks inversion. The space groups can also exhibit ferroelectricity. Research Details. The trihexagonal tiling has Schläfli symbol of r{6,3}, or Coxeter diagram, , symbolizing the fact that it is a rectified hexagonal tiling, {6,3}.Its symmetries can be described by the wallpaper group p6mm, (*632), and the tiling can be derived as a Wythoff construction within the reflectional fundamental domains of this group. Abstract 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.
