Interacting molecules on the surface of a dx2-y2-wave superconductor -: art. no. 224503

We study interacting molecules on the surface of a d(x2-y2)-wave superconductor. We show that the interplay between the molecules' excitation spectrum and quantum interference of the scattered host electrons leads to a series of characteristic signatures and intriguing quantum effects in the superconductor's local density of states. We demonstrate that these effects give insight into both the nature of the superconducting pairing correlations and the intermolecular interactions.
