Electric-field-induced Majorana Fermions in Armchair Carbon Nanotubes
We consider theoretically an armchair carbon nanotube (CNT) in the presence of an electric field and in contact with an $s$-wave superconductor. We show that the proximity effect opens up superconducting gaps in the CNT of different strengths for the exterior and interior branches of the two Dirac points. For …
