Released power in a vortex-antivortex pairs annihilation process

Revista UIS Ingenierías, 2020
In this paper, we studied the power dissipation process of a Shubnikov vortex-antivortex pair in a mesoscopic superconducting square sample with a concentric square defect in presence of an oscillatory external magnetic field. The time-dependent Ginzburg-

Approximate inertial manifolds for nonlinear parabolic equations via steady-state determining mapping

International Journal of Mathematics and Mathematical Sciences, 1995
For nonlinear parabolic evolution equations, it is proved that, under the assumptions of local Lipschitz continuity of nonlinearity and the dissipativity of semiflows, there exist approximate inertial manifolds (AIM) in the energy space and that the ...

Generalized Ginzburg–Landau equations in high dimensions

, 2017
International audienceIn this work, we study critical points of the generalized Ginzburg–Landau equations in dimensions which satisfy a suitable energy bound, but are not necessarily energy-minimizers.

Stability of the Stochastic Ginzburg–Landau–Newell Equations in Two Dimensions

Axioms
This paper concerns the 2D stochastic Ginzburg–Landau–Newell equations with a degenerate random forcing. We study the relationship between stationary distributions which correspond to the original and perturbed systems and then prove the stability of the

Modeling ternary mixtures by mean-field theory of polyelectrolytes: Coupled Ginzburg–Landau and Swift–Hohenberg equations [PDF]

, 2012
The purpose of this work is to model ternary mixtures using the theory of pattern formation and of polyelectrolytes, with mean-field approximations. The model has two local, non-conserved order parameters.

Blow-up of solutions for weakly coupled systems of complex Ginzburg-Landau equations

Electronic Journal of Differential Equations, 2017
Blow-up phenomena of weakly coupled systems of several evolution equations, especially complex Ginzburg-Landau equations is shown by a straightforward ODE approach, not by the so-called test-function method used in [38] which gives the natural blow-up

Rotating superconductors: Ginzburg-Landau equations

, 2002
Superconductors put into rotation develope a spontaneous internal magnetic field (the “London field”). In this paper Ginzburg Landau equations for order parameter, field, and current distributions for superconductors in rotation are derived.
