A Bound Preserving Energy Stable Scheme for a Nonlocal Cahn–Hilliard Equation

open access: yesComptes Rendus. Mécanique
We present a finite-volume based numerical scheme for a nonlocal Cahn–Hilliard equation which combines ideas from recent numerical schemes for gradient flow equations and nonlocal Cahn–Hilliard equations.

Pullback Attractor for Nonautonomous Ginzburg-Landau Equation with Additive Noise

open access: yesAbstract and Applied Analysis, 2014
Long time behavior of stochastic Ginzburg-Landau equations with nonautonomous deterministic external forces, dispersion coefficients, and nonautonomous perturbations is studied. The domain is taken as a bounded interval I in R.

Global solutions for 2D coupled Burgers-complex-Ginzburg-Landau equations

open access: yesElectronic Journal of Differential Equations, 2015
In this article, we study the periodic initial-value problem of the 2D coupled Burgers-complex-Ginzburg-Landau (Burgers-CGL) equations. Applying the Brezis-Gallout inequality which is available in 2D case and establishing some prior estimates, we ...

Well-posedness for one-dimensional anisotropic Cahn-Hilliard and Allen-Cahn systems

open access: yesElectronic Journal of Differential Equations, 2015
Our aim is to prove the existence and uniqueness of solutions for one-dimensional Cahn-Hilliard and Allen-Cahn type equations based on a modification of the Ginzburg-Landau free energy proposed in [8].

A fourth-order linearized difference scheme for the coupled space fractional Ginzburg–Landau equation

open access: yesAdvances in Difference Equations, 2019
In this paper, the coupled space fractional Ginzburg–Landau equations are investigated numerically. A linearized semi-implicit difference scheme is proposed.

Uniform regularity for a mathematical model in superfluidity

open access: yesElectronic Journal of Differential Equations, 2018
We prove uniform-in-$\mu$ estimates for a mathematical model in superfluidity. Consequently, the limit as $\mu\to0$ can be established.

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

open access: yesInternational 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 ...

Entanglement of Vortices in the Ginzburg–Landau Equations for Superconductors

open access: yesCommunications in Mathematical Physics
AbstractIn 1988, Nelson proposed that neighboring vortex lines in high-temperature superconductors may become entangled with each other. In this article we construct solutions to the Ginzburg–Landau equations which indeed have this property, as they exhibit entangled vortex lines of arbitrary topological complexity.

Released power in a vortex-antivortex pairs annihilation process

open access: yesRevista 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-

The pollution effect for the Ginzburg-Landau equation.

open access: yesCoRR
In this paper, we investigate the approximation properties of solutions to the Ginzburg-Landau equation (GLE) in finite element spaces. Special attention is given to how the errors are influenced by coupling the mesh size h and the polynomial degree p of the finite element space to the size of the so-called Ginzburg-Landau material parameter κ.
