A Relation between the Resonance Neutron Peak and ARPES Data in Cuprates

Open access
Abanov, Ar., Chubukov, Andrey V.·1999·Physical Review Letters

Abstract

We argue that the resonant peak observed in neutron scattering experiments on superconducting cuprates and the peak/dip/hump features observed in ARPES measurements are by-products of the same physical phenomenon. Both are due to feedback effects on the damping of spin fluctuations in a $d$-wave superconductor. We solve a set of coupled integral equations for fermionic and bosonic propagators, and show that the dynamical spin susceptibility below ${T}_{c}$ possesses the resonance peak at ${\ensuremath{\Omega}}_{\mathrm{res}}\ensuremath{\propto}{\ensuremath{\xi}}^{\ensuremath{-}1}$. The scattering of these magnetic excitations by electrons gives rise to a peak/dip/hump behavior of the electronic spectral function, the peak-dip separation is exactly ${\ensuremath{\Omega}}_{\mathrm{res}}$.

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.
