Resumen
BARBA-ORTEGA, José José; VALBUENA-NINO, Ely Dannier y RINCON-JOYA, Miryam. Transport phenomena in superconductors: kinematic vortex. Iteckne [online]. 2017, vol.14, n.1, pp.11-16. ISSN 1692-1798.
The phenomenological Ginzburg-Landau theory (FGLT) is a strong tool in understanding the physics of the superconductors at low critical temperature in the presence of applied fields and currents. The FGLT is derived from the second order transition theory of Landau based on critical phenomena, leading to a set of two coupled nonlinear Ginzburg-Landau equations (GLE). In this paper, we solve the GLE to a superconducting slab of Al in presence of applied current j at zero magnetic fields. We have analysed the appearance and subsequent annihilation of vortex-anti-vortex pairs in the middle of the sample at an external applied current j1. A small resistivity is found in Meissner range in the current-voltage curve at j ≤ j1.
