# Quantum spin liquids: a review

@article{Savary2016QuantumSL, title={Quantum spin liquids: a review}, author={Lucile Savary and Leon Balents}, journal={Reports on Progress in Physics}, year={2016}, volume={80} }

Quantum spin liquids may be considered ‘quantum disordered’ ground states of spin systems, in which zero-point fluctuations are so strong that they prevent conventional magnetic long-range order. More interestingly, quantum spin liquids are prototypical examples of ground states with massive many-body entanglement, which is of a degree sufficient to render these states distinct phases of matter. Their highly entangled nature imbues quantum spin liquids with unique physical aspects, such as non…
