p-wave triggered superconductivity in single layer graphene on an electron-doped oxide superconductor

Physical systems supporting unconventional superconducting states, where electrons pair up in a parallel spin (spin-triplet) state other than in a conventional antiparallel spin (spin-singlet) state, have been extensively investigated over the past few years due to their potential application in spintronics devices operating in the superconducting regime [1]. These systems include $p$-wave superconductors, where pairing correlations are intrinsically in a spin-triplet state, and magnetically inhomogeneous ferromagnet/$s$-wave superconductor heterostructures [2-3]. In this talk, I will discuss our low-temperature scanning tunneling spectroscopy results, which demonstrate evidence for the emergence of a $p$-wave superconducting state in single-layer graphene (SLG) proximity-coupled to the electron-doped high-temperature superconductor Pr$_{1.85}$Ce$_{0.15}$CuO$_{4\, }$[4].
