It is proved that a two dimensional evolutionary Ginzburg-Landau superconductivity model is an approximation of acorresponding thin plate three dimensional superconductivity model when the thickness of the plate uniformly approaches zero Some relatedtopics such as existence ofweak solutions to the three dimensional variable thickness model and the convergence when the variable thicknesstends to zero are discussed A numencal experiment using the now model is reported © Elsevier, ParisMOS subject classification: 35K55, 82D55Résumé — On introduit un modèle de superconductivité bi-dimensionnel instatwnnaire de type Ginzburg-Landau comme la limite dumodèle de plaque mince tn-dimensionnel correspondant quand Vépaisseur de la plaque tend vers zéro On discute l'existence de solutionsfaibles du modèle et leur limite quand l'épaisseur tend vers zéro On présente une expérience numérique qui utilise le nouveau modèle© Elsevier, Pans

In this paper, we study the single-vortex solutions of a two-dimensional high-κ high-field Ginzburg-Landau model of superconductivity with a constant applied current. Under a nondegeneracy condition and for appropriate ranges of the applied magnetic field and applied current, we construct some special solutions which, up to a constant shift of phase in time, are the stationary solutions of the ...

متن کاملOn the Crossover from Bcs Superconductivity to Bose Condensation
We outline a microscopic approach to the superconducting fluctuations and pairing correlations in the attractive Hubbard model above Tc, using the functional integral method. A crossover from BCS superconductivity to Bose condensation of preformed pairs is studied by constructing the appropriate Ginzburg–Landau functionals. The differences between the lattice and the continuum models are discus...
