Convexification of a Complex Ginzburg–Landau Equation with Reversed Time Using a New Carleman Estimate

Mathematics
In this paper, we propose a convexification method for the reversed-time problem of a complex Ginzburg–Landau equation by introducing a new Carleman estimate for the complex Ginzburg–Landau operator, which holds on an arbitrary time interval.

Quantization effects for multi-component Ginzburg-Landau vortices

Advanced Nonlinear Studies
In this paper, we are concerned with n-component Ginzburg-Landau equations on R2 ${\mathbb{R}}^{2}$ . By introducing a diffusion constant for each component, we discuss that the n-component equations are different from n-copies of the single Ginzburg ...

The interaction of free Rossby waves with semi-transparent equatorial waveguide – wave-mean flow interaction [PDF]

Nonlinear Processes in Geophysics, 2009
Nonlinear interactions of the barotropic Rossby waves propagating across the equator with trapped baroclinic Rossby or Yanai modes and mean zonal flow are studied within the two-layer model of the atmosphere, or the ocean. It is shown that the equatorial

Entanglement of Vortices in the Ginzburg–Landau Equations for Superconductors

Communications 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.

The pollution effect for the Ginzburg-Landau equation.

CoRR
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.
