C. Broholm, R. J. Cava, S. A. Kivelson, D. G. Nocera et al.

Short summary

Quantum spin liquids are exotic phases of matter with topological properties, exhibiting fractionalized excitations, though no material is definitively confirmed as a spin liquid.

Key points

  • Quantum spin liquids possess topological order and fractionalized excitations.
  • Excitations in spin liquids can behave as fractions of an electron.
  • No single material is universally accepted as a confirmed spin liquid.
  • Several materials exhibit properties suggestive of quantum spin liquids.

Abstract

Spin liquids are quantum phases of matter with a variety of unusual features arising from their topological character, including "fractionalization"-elementary excitations that behave as fractions of an electron. Although there is not yet universally accepted experimental evidence that establishes that any single material has a spin liquid ground state, in the past few years a number of materials have been shown to exhibit distinctive properties that are expected of a quantum spin liquid. Here, we review theoretical and experimental progress in this area.
