چکیده

A formal asymptotic expansion is used to simplify the Ginzburg-Landau model of superconductivity in the limit of large values of the Ginzburg-Landau parameter and high applied magnetic field strengths. The convergence of solutions of the full Ginzburg-Landau equations to solutions of the leading order equations in the hierarchy is demonstrated for both boundary value and periodic problems. The results of computational experiments using the full Ginzburg-Landau model and the leading order model are given. These indicate that the simplified model yields solutions that are accurate approximations to solutions of the full model equations even for moderate values of the Ginzburg-Landau parameter.

Analysis and approximation of optimal control problems for a simplified Ginzburg-Landau model of superconductivity

This paper is concerned with optimal control problems for a Ginzburg-Landau model of superconductivity that is valid for high values of the Ginzburg-Landau parameter and high external fields. The control is of Neumann type. We first show that optimal solutions exist. We then show that Lagrange multipliers may be used to enforce the constraints and derive an optimality system from which optimal ...

Chern-simons Vortices

In (2 + 1) dimensions, the Maxwell term − 1 4 F αβ F αβ can be replaced by the Chern-Simons three-form (κ/4)ǫ αβγ A α F βγ , yielding a novel type of 'electromagnetism'. This has been proposed for studying the Quantum Hall Effect as well as High-Temperature Superconductivity. The gauge field can be coupled to a scalar field either relativistically or non-relativistically. In both cases, one adm...

Exact solutions of the 2D Ginzburg-Landau equation by the first integral method

The first integral method is an efficient method for obtaining exact solutions of some nonlinear partial differential equations. This method can be applied to non integrable equations as well as to integrable ones. In this paper, the first integral method is used to construct exact solutions of the 2D Ginzburg-Landau equation.

The Density of Superconductivity in the Bulk Regime

In the asymptotic limit of a large Ginzburg-Landau parameter, we give a new asymptotic formula for the L-norm of the Ginzburg-Landau order parameter. The formula is valid in the bulk regime where the intensity of the applied magnetic eld is of the same order as the Ginzburg-Landau parameter and strictly below the second critical eld. Our formula complements the celebrated one of Sandier-Serfaty...

Non-linear Surface Superconductivity in Three Dimensions in the Large Κ Limit

The Ginzburg–Landau model of superconductivity is considered in three dimensions. We show, for smooth bounded domains, that the superconductivity order parameter decays exponentially fast away from the boundary as the Ginzburg–Landau parameter κ tends to infinity. We prove this result for applied magnetic fields satisfying |hex| − κ κ1/2. Additionally, we prove that for applied fields greater t...
