Identifying Collective Modes via Impurities in the Cuprate Superconductors
Roy H. Nyberg, Enrico Rossi, Dirk K. Morr
We show that the pinning of collective charge and spin modes by impurities in the cuprate superconductors leads to qualitatively different fingerprints in the local density of stat…

Molecular Nanostructures on the Surface of a d_(x2-y2)-Superconductor
Roy H. Nyberg, Dirk K. Morr
We study molecular nanostructures on the surface of a d_(x2-y2)-wave superconductor. We show that the interplay between the molecular nanostructure's internal excitation spectrum a…

Localized Bosonic Modes in Superconductors
Dirk K. Morr, Roy H. Nyberg
We show that a localized bosonic mode acts as a new type of "defect" in s- and d_{x^2-y^2}-wave superconductors. The mode induces bound or resonance states, whose spectral signatur…
