Inspired by recent experimental discoveries of superconductivity inchirally-stacked and twisted multilayer graphene, we study models of $f$-wavesuperconductivity on the honeycomb lattice with arbitrary numbers of layers.These models respect a mirror symmetry that allows classification of the bandsby a mirror-projected winding number $\nu_\pm$. For odd numbers of layers, thesystems are topologically nontrivial with $\nu_\pm = \pm 1$. Along eachmirror-preserving edge in armchair nanoribbons, there are two protectedMajorana zero modes. These modes are present even if the sample is finite inboth directions, such as in rectangular and hexagonal flakes. Crucially, zeromodes can also be confined to vortex cores, which can be created by a magneticfield or localized magnetic impurities and accessed by local scanning probes.Finally, we apply these models to twisted bilayer and trilayer systems, whichalso feature boundary-projected and vortex-confined zero modes. Since vorticesare experimentally accessible, our study suggests that superconductingmultilayer graphene systems are promising platforms to create and manipulateMajorana zero modes.
