## Abstract

We present an interpretation of the recent neutron data on the commensurate and incommensurate spin fluctuations found in YBa\_2d$Cu\_3O\_{6+y} based on a special configuration of the electronic dispersion and intervention from the d\_{x^2-y^2}-wave superconducting phase. The observed switch over between the commensurate and incommensurate fluctuation spectra at the change of frequency or temperature is naturally accounted within this scenario.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
