Query: Nucleation and Growth of Normal Phase in Thin Superconducting Strips   We investigate the kinetics of normal phase nucleation and flux line
condensation in the type-II superconductors by numerical study of the
time-dependent Ginzburg-Landau equation. We have shown that under the
sufficient transport current the normal phase nucleates in the superconducting
strips in a form of the macroscopic droplets having the multiple topological
charge. We discuss the stability and the dynamics of the droplets. We found
that pinning suppresses the droplet formation.
