Abstract: | The supercurrent for the surface superconductivity of a flat-band multilayered rhombohedral graphene is calculated. Despite
the absence of dispersion of the excitation spectrum, the supercurrent is finite. The critical current is proportional to
the zero-temperature superconducting gap, i.e., to the superconducting critical temperature and to the size of the flat band
in the momentum space. |
