Spin-Liquid Ground State of the S = 1/2 Kagome Heisenberg Antiferromagnet
TLDR
This work uses the density matrix renormalization group to perform accurate calculations of the ground state of the nearest-neighbor quantum spin S = 1/2 Heisenberg antiferromagnet on the kagome lattice and provides strong evidence that, for the infinite two-dimensional system, the groundState of this model is a fully gapped spin liquid.Abstract:
We use the density matrix renormalization group to perform accurate calculations of the ground state of the nearest-neighbor quantum spin S = 1/2 Heisenberg antiferromagnet on the kagome lattice. We study this model on numerous long cylinders with circumferences up to 12 lattice spacings. Through a combination of very-low-energy and small finite-size effects, our results provide strong evidence that, for the infinite two-dimensional system, the ground state of this model is a fully gapped spin liquid.read more

A Practical Introduction to Tensor Networks: Matrix Product States and Projected Entangled Pair States
TL;DR: This is a partly non-technical introduction to selected topics on tensor network methods, based on several lectures and introductory seminars given on the subject, that should be a good place for newcomers to get familiarized with some of the key ideas in the field.

Quantum spin liquid states
TL;DR: In this paper, a review of the physics of spin liquid states is presented, including spin-singlet states, which may be viewed as an extension of Fermi liquid states to Mott insulators, and they are usually classified in the category of SU(2), U(1), or Z2.

Fractionalized excitations in the spin-liquid state of a kagome-lattice antiferromagnet

TL;DR: At low temperatures, neutron scattering measurements on single-crystal samples of the spin-1/2 kagome-lattice antiferromagnet ZnCu3(OD)6Cl2 (also called herbertsmithite), which provide striking evidence for this characteristic feature of spin liquids, find that the spin excitations form a continuum, in contrast to the conventional spin waves expected in orderedAntiferromagnets.

Resonating valence bonds: A new kind of insulator?
TL;DR: In this article, the possibility of a new kind of electronic state corresponding roughly to Pauling's idea of resonance valence bonds in metals was pointed out, and an estimate of its energy was made in one case.
