For newly discovered 'quantum spin liquid', the beauty is in its simplicity.

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. This we provide via an explicit construction, starting from reformulating a microscopic model for a CSL as a lattice gauge theory, and.

Spin-Liquid State in the S 1 2 Hyperkagome Antiferromagnet.

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). Our work is motivated by the recent synthesis of a distorted SKL compound mentioned. A watershed in the ﬁeld of frustrated magnetism. The spin-1 2 states on the Cu sites, which sit on a kagome lattice, are characterized by a sizable superexchange interaction of about 200 K, but the spins do not order or freeze down to the lowest temperatures measured, suggesting that the ground state is a quantum spin liquid [2,3]. Fig 2. Physics of creating spin-pairs in a frustrated lattice. Ground state atoms (green dots) are arranged in an edge-Kagome lattice, where each atom sits in the middle of the edges of a Kagome lattice.Once a coherent laser field drives all atoms towards their Rydberg state, Rydberg-Rydberg interactions start playing a role, which prevents neighboring atoms to be both in the Rydberg states.

Z2 spin liquid in kagome Heisenberg antiferromagnet | PIRSA.

Seen in triangular and kagome antiferromagnets reported to have a spin-liquid ground state. These results strongly suggest that the ground state of Na 4Ir 3O 8 is a three dimensional manifestation of a spin liquid. DOI: 10.1103/PhysRevLett.99.137207 PACS numbers: 75.40.Cx, 75.47.Pq The experimental realization of a quantum spin liquid in. The properties of ground state of spin-\frac{1}{2}12 kagome antiferromagnetic Heisenberg (KAFH) model have attracted considerable interest in the past few decades, and recent numerical simulations reported a spin liquid phase. The nature of the spin liquid phase remains unclear. For instance, the interplay between symmetries and Z_2Z2 topological order leads to different types of Z_2Z2 spin.

Quantum spin liquid state pathway emerges - Physics World.

The Spin-1/2 Kagome Lattice For S=1=2 kagome, the leading proposals are the 36-site VBS and the U(1) Dirac spin liquid. The 36-site VBS pattern is found in series expansion [Singh and Huse, PRB 76, 180407 (2007)] and entanglement renormalization [Evenbly and Vidal, arXiv:0904.3383]. From VMC, the U(1) Dirac spin liquid (DSL). Researchers created a synthetic material out of 1 billion tiny magnets. It now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state. Quantum spin liquid was first predicted by physicist Philip W. Anderson about 50 years ago, in 1973, but has never been observed in experiments until now.... In our approach, arrays of atoms were placed on the links of a kagome lattice, and evolution under Rydberg blockade created frustrated quantum states with no local order. The onset of a.

Kagome spin liquid: a deconfined critical phase driven by $U(1)$ gauge.

The observation of the thermal version of the Hall effect in a spin-liquid state of a quantum magnet with frustrated two-dimensional kagomé structure suggests the emergence of nontrivial elementary excitations in the gapless SL state which feel the presence of fictitious magnetic flux. Significance The Hall effect is due to the nature of the charge carriers in a conductor, which experience. Kagome lattices are one of the simplest structures believed to possess a spin liquid state, and the new findings, revealed by neutron scattering, indeed show striking evidence for a fundamental prediction of spin liquid physics. Generally, magnetism results from the magnetic moment, also called spin, of electrons within atoms.

Y1 - 2014/9/15. N2 - We revisit the description of the low-energy singlet sector of the spin-12 Heisenberg antiferromagnet on kagome in terms of an effective quantum dimer model. With the help of exact diagonalizations of appropriate finite-size clusters, we show that the embedding of a given process in its kagome environment leads to dramatic.

Kapellasite: a kagome quantum spin liquid with competing interactions.

Spin liquid (QSL), is shown in the kagome Heisenberg antiferromagnet (KHA) by various numerical calculations [1-8]. A lot of QSLs are theoretically suggested as the ground state of the KHA such as Z2 spin liquids [2,9,10], topological spin liquids [3], Dirac spin liquids [4,6-8], and chiral spin liquids [11]. These different QSLs are charac.

Electron Doping a Kagome Spin Liquid - Physical.

Kagome lattices are one of the simplest structures believed to possess a spin liquid state, and the new findings, revealed by neutron scattering, indeed show striking evidence for a fundamental. In conclusion, we have successfully synthesized a new kagome compound Cu 3 Zn(OH) 6 FBr and its quantum spin liquid ground state is verified in our thermodynamical measurements. Our 19 F NMR data reveals a gapped spin-liquid ground state for Cu 3 Zn(OH) 6 FBr, similar to previous 17 O NMR results on herbertsmithite. Most importantly, we provide. On the kagome MðDÞ (Sec. SIII of the SM [20]). Our kagome results lie well below this bound, but with no evidence for deviation from a similar algebraic form, reinforcing the conclusion that the ground state of the KHAF is a gapless spin liquid. For full rigor we consider every aspect of the PESS procedure. Full-update calculations confirm.
