Colloquium: Herbertsmithite and the search for the quantum spin liquid.
We demonstrate that herbertsmithite#x27;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. Specifically, the low-energy effective theory of a quantum spin liquid is a deconfined gauge theory, that is, one in which spinons are free to propagate and thus not bound in pairs that would carry integer spin. The particle physics analog would be a phase with free quarks.. The results also serve as a hallmark of the quantum spin-liquid state in herbertsmithite. Main In a spin liquid, the atomic magnetic moments are strongly correlated but do not order or freeze even.

A New State Of Matter: Quantum Spin Liquids Explained.
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]. Apr 25, 2022 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. 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.
Heavy fermion spin liquid in herbertsmithite - ScienceDirect.
Quantum spin liquids are frequently found in a class of materials known as frustrated magnets. In a conventional magnet, the interactions between spins result in stable formations, known as their long-range order, in which the magnetic directions of each individual electron is aligned. Herbertsmithite, a candidate quantum spin liquid source.
For newly discovered #x27;quantum spin liquid#x27;, the beauty is in its simplicity.
Among the inorganic spin-liquid candidates, the rhombohedral herbertsmithite ZnCu 3 OH 6 Cl 2 scored highest in popularity. As depicted in figure 2, the copper ions form an almost perfect kagome lattice [], i.e. corner sharing triangles in the plane with strong antiferromagnetic superexchange J of approximately 200 K. No magnetic order is detected all the way down to T = 50 mK [27, 28]. 2021-Heat Transport in Herbertsmithite:Can a Quantum Spin Liquid Survive D : Adobe PDF. 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.

Heat Transport in Herbertsmithite: Can a Quantum Spin Liquid Survive Disorder? Abstract 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. Thus, QSL of ZnCu 3 OH 6 Cl 2 can be viewed as a strongly correlated quantum spin liquid SCQSL that behaves like that of the HF metal YbRh 2 Si 2, exhibiting a gapless behavior in high magnetic fields up to 18 T. We now construct the schematic phase diagram of ZnCu 3 OH 6 Cl 2, reported in Fig. 3. 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.

Identification of Strongly Correlated Spin Liquid in Herbertsmithite.
Named after a mineralogist, Herbertsmithite was proposed to be a quantum spin liquid by Daniel Nocera and Young Lee of the Massachusetts Institute of Technology MIT in 2007. quot;The structural simplicity of Herbertsmithite is valuable if we are to put the quantum spin liquid to useas proposed for information processing, for example,quot; he says. quot;Complex chemistry usually brings disorder, but this material is relatively simple, so it realizes the quantum spin liquid with higher fidelity.quot.
Scaling in dynamic susceptibility of herbertsmithite and heavy-fermion.
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. Herbertsmithite is believed to be a two-dimensional quantum spin liquid: a solid material whose atomic spins continue to have motion, even at absolute zero temperature. This exciting research has potential to improve technology, another wonderful scientific advance related to the study of mineralogy.

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.

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 present a theory of the dynamic magnetic susceptibility of quantum spin liquid. The obtained results are in good agreement with experimental facts collected on herbertsmithite Z n C u 3 O H 6 C l 2 and on heavy-fermion metals, and allow us to predict a new scaling in magnetic fields in the dynamic susceptibility.
