PHYSICAL REVIEW B, Volume 65, Issue 22, pp. ? - ? (4). https://doi.org/10.1103/PhysRevB.65.2205092469-99502469-9969https://hdl.handle.net/2144/37196We present a theory of the pinning of dynamic spin-density-wave (SDW) fluctuations in a d-wave superconductor by local imperfections that preserve spin-rotation invariance, such as impurities or vortex cores. The pinning leads to static spatial modulations in spin-singlet observables, while the SDW correlations remain dynamic: these are the “Friedel oscillations” of a spin-gap antiferromagnet. We connect the spectrum of these modulations as observed by scanning tunnelling microscopy to the dynamic spin structure factor measured by inelastic neutron scattering.4 p.en-UShttps://journals.aps.org/prb/aboutScience & technologyPhysical sciencesMaterials science, multidisciplinaryPhysics, appliedPhysics, condensed matterMaterials sciencePhysicsT-J modelStriped phaseLandau theoryVortexStatesAntiferromagnetsArticle10.1103/PhysRevB.65.2205090000-0002-5549-7400 (Polkovnikov, A)54814
