Query: Topological phase in a $d_{x^2-y^2}+(p+ip)$ superconductor in presence
  of spin-density-wave   We consider a mean-field Hamiltonian for a $d_{x^2-y^2}+(p+ip)$
superconductor(SC) in presence of spin-density-wave(SDW) order. This is due to
the fact that the non-commutativity of any two orders produces the third one.
The energy spectrum of such a Hamiltonian is shown to be gapped and it yields a
topological phase in addition to the conventional one. A phase diagram
characterizing different topological phases is construted. The Chern numbers
and hence the nature of the topological phases are determined. The edge state
spectrum and the possibility of whether the vortex state harbouring the zero
modes are discussed.
