Spin liquids in frustrated magnets

Balents, Leon·2010·Nature

Abstract

Frustrated magnets are materials in which localized magnetic moments, or spins, interact through competing exchange interactions that cannot be simultaneously satisfied, giving rise to a large degeneracy of the system ground state. Under certain conditions, this can lead to the formation of fluid-like states of matter, so-called spin liquids, in which the constituent spins are highly correlated but still fluctuate strongly down to a temperature of absolute zero. The fluctuations of the spins in a spin liquid can be classical or quantum and show remarkable collective phenomena such as emergent gauge fields and fractional particle excitations. This exotic behaviour is now being uncovered in the laboratory, providing insight into the properties of spin liquids and challenges to the theoretical description of these materials.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The equally weighted superposition of all different localized valence-bond states corresponds to a quantum spin liquid, the resonating valence-bond state.

    “In general, the equally weighted superposition of all different localized valence-bond states corresponds to a quantum spin liquid, the so-called resonating valence-bond state[37, 38].”
  • Tuning the coupling ratio to κ = -∞ results in the equally weighted superposition |Φ×> + |Φ||>, whereas κ = 1 leads to the resonating valence-bond state |Φ=> + |Φ||>.

    “Tuning the coupling ratio to κ = -∞ results in the equally weighted superposition | Φ × 〉 + ∣ ∣ Φ ‖ 〉 , whereas κ = 1 leads to the interesting resonating valence-bond state[37-39] | Φ = 〉 + ∣ ∣ Φ ‖ 〉 .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
