Herbertsmithite - The Mineral with a unique flow, different magnetism.
Herbertsmithite is an insulator, not a superconductor, but quantum spin liquid theory predicts that doping the crystal (such as substituting its chlorine with sulfur) could transform it into a superconductor. Han, Lee and their colleagues were able to synthesize about a third of a gram of pure single crystal herbertsmithite in their recent work.
Heat Transport in Herbertsmithite: Can a Quantum Spin Liquid Survive.
Thus, when analyzing the physics of quantum spin liquid in the herbertsmithite, it is of crucial importance to verify the existence of a spin gap by experimental and theoretical studies, for the.
Herbertsmithite - Wikipedia.
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. The peculiar phase diagram of this organic quantum spin liquid compound was first thoroughly mapped using muon spin spectroscopy. Herbertsmithite Herbertsmithite is one of the most extensively studied QSL candidate materials. It is a mineral with chemical composition ZnCu 3 (OH) 6 Cl 2 and a rhombohedral crystal structure.
Quantum spin liquids - Science.
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.
A new state of matter: Quantum spin liquids explained.
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.
Thermodynamic, Dynamic, and Transport Properties of Quantum Spin Liquid.
Abstract: 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. Our calculations unveil the fundamental properties of QSL, forming strongly correlated Fermi system located at a fermion condensation quantum phase transition.
Rich nature of Van Hove singularities in Kagome.
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. In two dimensions, the classic example. 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.
A new spin on superconductivity? | MIT News | Massachusetts Institute.
The most famous example is the copper-based mineral Herbertsmithite, for which there is significant evidence to suggest that a quantum spin liquid state exists within the frustrated magnetic. 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. 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.
Universal Behavior of Quantum Spin Liquid and Optical Conductivity 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.
Colloquium: Herbertsmithite and the search for the quantum spin liquid.
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]). 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.).

In this work, we investigate possible quantum spin liquid phases in the presence of spin-rotation symmetry-breaking perturbations such as Dzyaloshinskii-Moriya (DM) and Ising interactions, as well as second-neighbor antiferromagnetic Heisenberg interactions. Ex-periments suggest that such perturbations are likely to be present in Herbertsmithite.
Strongly correlated quantum spin liquid in herbertsmithite.
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. May 02, 2022 ยท While the possibility of such a quantum spin liquid has been entertained in seminal theoretical studies before 15,20, our present work firmly identifies Ce 2 Zr 2 O 7 as a very promising host for.

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.
