The dynamic theory of helical vortices in a superconducting wire subjected to a longitudinal bias current and axial magnetic field has been developed. Two distinct regimes are identified: vanishing and spreading. The helix radius and the voltage induced by the helix motion are obtained as functions
Size and surface dynamical effects are investigated in thin superconducting stripes with variable width. We perform numerical simulations of the vortex dynamics, with the inclusion of the surface confining potential and a random distribution of pinning centers. To fully characterize the vortex flow,
