While an overarching principle specifying the precise microscopic coupling scenarios for which quantum spin-liquid behavior arises is unknown, it is well-established that they are preferably found in spin systems where the corresponding classical limit of spin magnitudes [Formula: see text] exhibits a macroscopic ground state degeneracy, so-called classical spin liquids. Spiral spin liquids represent a special family. Classical spin liquid: Exact solution for the infinite-component antiferromagnetic model on the kagomé lattice. DA Garanin, B Canals.

Compounds are referred to as classical spin liquids [4,5],as cooperative paramagnets [2],ormerelyashavingspin-liquid-like phases [6], although no clear definition of these terms is readily available. The classical triangular-lattice Heisenberg antiferromag-net with nearest-neighbor exchange interactions (TLHA) is.

Classical and quantum spin dynamics of the honeycomb Γ model.

We find that the recombination of topological charges gives rise to a yet unexplored classical spin liquid. This spin liquid is characterized by an extensive residual entropy, as well as the formation of hexamers of same-sign topological charges. The emergence of hexamers is reflected to a half-moon signal in the magnetic structure factor. Gao, B. et al.

Classical fluctuations dominate for large spins (those with a size, S, much larger than the minimum size of ½) and are driven by thermal energy. Spins can. Computational detective work by U.S. and German physicists has confirmed that cerium zirconium pyrochlore is a 3D quantum spin liquid.

Phys. Rev. Lett. 127, 157202 (2021) - Classical Spin Liquid State in.

Here we take the example of the classical spin liquid in a frustrated magnet with novel bond-dependent interactions to investigate the classical dynamics, and critically compare it with quantum dynamics in the same system. In particular, we focus on signatures in the dynamical spin structure factor. Oct 11, 2016 · Jammed Spin Liquid in the Bond-Disordered Kagome Antiferromagnet.

Thermodynamic quantities and correlation functions (CFs) of the classical antiferromagnet on the checkerboard lattice are studied for the exactly solvable infinite-component spin-vector model, D→∞. In contrast to conventional two-dimensional magnets with continuous symmetry showing extended short-range order at distances smaller than the correlation length, r≲ξc∝exp(T∗/T.

Spin correlations of quantum spin liquid and quadrupole-ordered states.

Apr 05, 2017 · We show that the off-diagonal exchange anisotropy drives Mott insulators with strong spin-orbit coupling to a classical spin liquid regime, characterized by an infinite number of ground states and Ising variables living on closed or open strings. Depending on the sign of the anisotropy, quantum fluctuations either fail to lift the degeneracy down to very low temperatures, or select noncoplanar. We obtain a classical spin liquid (CSL) phase by applying a magnetic field to the J 1 -J 2 -J 3 Ising model on a kagome lattice. As we proved in the previous study [Phys. Rev. Lett. 119, 077207 (2017)], this model realizes one species of CSL, the hexamer CSL, at the zero magnetic field, which consists of macroscopically degenerate spin configurations with mixed total magnetization, M.

A moderate 31p nmr line broadening reveals the development of anisotropic short-range correlations concomitantly with a gapless spin-lattice relaxation time t 1 ∼kbt /ℏs, which may point to the presence of a semiclassical nematic spin-liquid state predicted for the heisenberg kagome antiferromagnetic model or to the persistence of the zero-energy. We study the low-temperature behavior of the classical Heisenberg antiferromagnet with nearest neighbor interactions on the pyrochlore lattice. Because of geometrical frustration, the ground state of this model has an extensive number of degrees of freedom. We show, by analyzing the effects of small fluctuations around the ground-state manifold, and from the results of Monte Carlo and. Quantum spin liquids, which are spin versions of quantum matter, have been sought after in systems with geometrical frustration.

Comprehensive study of the dynamics of a classical Kitaev spin liquid.

At low temperatures it is known to support an exotic phase of matter, a classical spin liquid lacking any local order parameter, but instead being described by emergent gauge fields. We establish a new type of spin liquid ground state, "a jammed spin liquid", existing down to zero temperature in the bond-disordered kagome Heisenberg.
