In strongly correlated Dirac semimetals, orbital-singlet, spin-triplet superconducting pairing becomes possible. In this work, the authors predict doubly robust Majorana flat bands bound to the vortex line: confined between the projected nodes in type-I Dirac semimetals and spanning the entire one-dimensional Brillouin zone in type-II Dirac semimetals.
