Pinch point singularities, associated with flat band magnetic excitations, are tell-tale signatures of Coulomb spin liquids. While their properties in the presence of quantum fluctuations have been widely studied, the fate of the complementary non-analytic features -- shaped as half-moons and stars -- arising from adjacent shallow dispersive bands has remained unexplored. Here, we address this. Jun 26, 2022 May 10, 2022 Computational detective work by physicists has confirmed cerium zirconium pyrochlore is a 3D quantum spin liquid,...

Herbertsmithite and Zn-doped barlowite are two compounds for experimental realization of two- dimensional kagome spin liquids. Theoretically, it has been proposed that charge doping a quantum spin liquid gives rise to exotic metallic states, such as high-temperature superconductivity.

Rich nature of Van Hove singularities in Kagome.
The exploration of quantum spin liquids QSLs has been guided by different approaches including the resonating valence bond RVB picture, deconfined lattice gauge theories and the Kitaev model. More recently, a spin liquid ground state was numerically established on the ruby lattice, inspired by the Rydberg blockade mechanism. Here we unify these varied approaches in a single parent.

A numerical analysis suggests that the elusive ground state of the antiferromagnetic Heisenberg model for the kagome lattice is a gapless spin liquid. APS/ Alan Stonebraker. Figure 1:Liao and colleagues [ 1] performed a numerical simulation on an infinite kagome lattice green. As they turn up the value of a parameter D shown by the meter in. While the existence of a chiral spin liquid CSL on a class of spin-1/2 kagome antiferromagnets is by now well-established numerically, a controlled theoretical path from the lattice model leading to a low energy topological field theory is still lacking.
Time-reversal symmetry-breaking charge order in a kagome.
Exotic phases of matter known as spin ices are defined by frustrated spins that obey local quot;ice rulesquot;similar to electric dipoles in water ice. Physicists can define ice rules in two-dimensions. July 6, 2021 Abstract The ground state of the spin 1/2 kagome antiferromagnet remains uncertain despite decades of active research. Here we step aside from this debated question to address the ground-state nature of a related, and potentially just as rich, system made of corner-sharing triangles: the square-kagome lattice SKL. The spin-1/2 Heisenberg model on the kagome lattice, a two-dimensional lattice formed by corner sharing triangles, is an intensively studied frustrated model. From early on it was recognized that the ground state of the nearest neighbor kagome lattice antiferromagnet is a non-magnetic state, although it is not clear whether it is a QSL [ 4 ] or.

Herbertsmithite, ZnCu 3 OH 6 Cl 2, is a two-dimensional kagome lattice realization of a spin liquid, with evidence for fractionalized excitations and a gapped ground state.Such a quantum spin liquid has been proposed to underlie high-temperature superconductivity and is predicted to produce a wealth of new states, including a Dirac metal at 1 / 3 electron doping. This transformation requires us to consistently define a Chern-Simons term on the kagome lattice. We find that the chirality term leads to a chiral spin liquid even in the absence of an uniform magnetic field, with an effective spin Hall conductance of xys=12 in the regime of XY anisotropy.

Consider an equilateral triangle with three spins, one on each vertex. If each spin can take on only two values up or down, there are 2 3 = 8 possible states of the system, six of which are ground states. The two situations which are not ground states are when all three spins are up or are all down.
