Query: Edge properties of the chiral d-wave superconducting state in doped
  graphene   We investigate the effect of edges on the intrinsic electron-electron
interaction driven d-wave superconducting state in graphene doped close to the
van Hove singularity. While the bulk is in a chiral $d_{x^2-y^2}+id_{xy}$
state, the order parameter at any edge is enhanced and has
$d_{x^2-y^2}$-symmetry, with a decay length strongly increasing with weakening
superconductivity. No graphene edge is pair breaking for the $d_{x^2-y^2}$
state and we never find any localized zero-energy edge states. We find two
chiral edge modes which carry a spontaneous, but not quantized, quasiparticle
current related to the zero-energy momentum. Moreover, for realistic values of
the Rashba spin-orbit coupling, a Majorana fermion appears at the edge when
tuning a Zeeman field.
