•Voltage–current characterization of a mesoscopic p-wave superconducting sample.•Skyrmions and edge states are stabilized with an out-of-plane applied magnetic field.•In the resistive regime, moving skyrmions and the edge state behave distinctly different from the conventional kinematic vortices. In a mesoscopic sample of a chiral p-wave superconductor, novel states comprising skyrmions and edge states have been stabilized in out-of-plane applied magnetic field. Using the time-dependent Ginzburg–Landau equations we shed light on the dynamic response of such states to an external applied current. Three different regimes are obtained, namely, the superconducting (stationary), resistive (non-stationary) and normal regime, similarly to conventional s-wave superconductors. However, in the resistive regime and depending on the external current, we found that moving skyrmions and the edge state behave distinctly different from the conventional kinematic vortex, thereby providing new fingerprints for identification of p-wave superconductivity.
