Ergodicity for the stochastic Complex Ginzburg–Landau equations [PDF]

open access: yesAnnales de l'Institut Henri Poincare (B) Probability and Statistics, 2006
We study a stochastic complex Ginzburg--Landau (CGL) equation driven by a smooth noise in space and we establish exponential convergence of the Markovian transition semi-group toward a unique invariant probability measure. Since Doob Theorem does not seem not to be useful in our situation, a coupling method is used.

Blow-up for self-interacting fractional Ginzburg-Landau equation

open access: yes, 2017
The blow-up of solutions for the Cauchy problem of fractional Ginzburg-Landau equation with non-positive nonlinearity is shown by an ODE argument. Moreover, in one dimensional case, the optimal lifespan estimate for size of initial data is obtained ...

Ginzburg-Landau-type theory of non-polarized spin superconductivity

open access: yes, 2017
Since the concept of spin superconductor was proposed, all the related studies concentrate on spin-polarized case. Here, we generalize the study to spin-non-polarized case.

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

open access: yesNonlinear 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

On the validity of the degenerate Ginzburg-Landau equation [PDF]

open access: yes, 1996
The Ginzburg{Landau equation which describes nonlinear modulation of the amplitude of the basic pattern does not give a good approximation when the Landau constant (which describes the in uence of the nonlinearity) is small.
