We study a one-dimensional system of spin-orbit coupled Dirac electrons with $s$-wave superconducting pairing. Both lattice and continuum models are studied. In the lattice model, we find that zero energy end modes appear provided that the $s$-wave pairing has an extended form, and the nearest-neighbor pairing is larger than the on-site pairing. We confirm this both numerically and analytically by calculating the winding number. We find that the continuum model also has zero energy end modes…
