Claims

C1strongest claim

Our neutron scattering observations and the strange metal behaviour are consistent with a spin density wave quantum phase transition in a metal with spatial disorder in the tuning parameter. Numerical computations using a theory of spin density waves in a disordered metal yield an extended 'Griffiths phase' with scaling properties in agreement with experimental observations.

C2weakest assumption

The observed neutron scattering intensity and its temperature dependence are produced by critical fluctuations from an underlying spin density wave quantum phase transition (rather than other mechanisms such as stripe order or phonons), and the spatial disorder model parameters can be chosen such that the computed Griffiths phase scaling matches the data without additional ad hoc adjustments.

C3one line summary

Neutron scattering reveals dynamical scaling of critical spin fluctuations across the LSCO superconducting dome, consistent with a disordered spin density wave quantum phase transition explaining strange metal behavior.
