Double Andreev reflections and double normal reflections in nodal-line semimetal-superconductor junctions

10 Mar 2020 Cheng Qiang Hou Zhe Sun Qing-Feng

We study systematically the scattering processes and the conductance spectra in nodal-line semimetalsuperconductor junctions using the extended Blonder-Tinkham-Klapwijk theory. The coexistence of peculiar quadruple reflections are found, which are the specular normal reflection, the retro-normal reflection, the specular Andreev reflection and the retro-Andreev reflection...
