Query: Electronic properties of emergent topological defects in chiral $p$-wave
  superconductivity   Chiral $p$-wave superconductors in applied magnetic field can exhibit more
complex topological defects than just conventional superconducting vortices,
due to the two-component order parameter (OP) and the broken time-reversal
symmetry. We investigate the electronic properties of those exotic states, some
of which contain clusters of one-component vortices in chiral components of the
OP and/or exhibit skyrmionic character in the \textit{relative} OP space, all
obtained as a self-consistent solution of the microscopic Bogoliubov-de Gennes
equations. We reveal the link between the local density of states (LDOS) of the
novel topological states and the behavior of the chiral domain wall between the
OP components, enabling direct identification of those states in scanning
tunneling microscopy. For example, a skyrmion always contains a closed chiral
domain wall, which is found to be mapped exactly by zero-bias peaks in LDOS.
Moreover, the LDOS exhibits electron-hole asymmetry, which is different from
the LDOS of conventional vortex states with the same vorticity. Finally, we
present the magnetic field and temperature dependence of the properties of a
skyrmion, indicating that this topological defect can be surprisingly large in
size, and can be pinned by an artificially indented non-superconducting closed
path in the sample. These features are expected to facilitate the experimental
observation of skyrmionic states, thereby enabling experimental verification of
chirality in emerging superconducting materials.
