The close proximity between graphene sheets and monolayers of 2D superconductors can lead to hybridization between their collective excitations. Heterostructures formed by combinations of graphene sheets and 2D superconductor monolayers show distinct features on the near-field reflection coefficient that can be observed in scanning near-field microscopy experiments, providing a promising platform for probing the many-body physics of superconductors.
We explore ways in which the close proximity between graphene sheets and monolayers of 2D superconductors can lead to hybridization between their collective excitations. We consider heterostructures formed by combinations of graphene sheets and 2D superconductor monolayers. The broad range of energies in which the graphene plasmon can exist, together with its tunability, makes such heterostructures promising platforms for probing the many-body physics of superconductors. We show that the hybridization between the graphene plasmon and the Bardasis-Schrieffer mode of a 2D superconductor results in clear signatures on the near-field reflection coefficient of the heterostructure, which in principle can be observed in scanning near-field microscopy experiments.
