Unstable manifolds and Schroedinger dynamics of Ginzburg-Landau vortices

open access: yes, 2002
The time evolution of several interacting Ginzburg-Landau vortices according to an equation of Schroedinger type is approximated by motion on a finite-dimensional manifold. That manifold is defined as an unstable manifold of an auxiliary dynamical system,

BIFURCATION TO CHAOS IN THE СOMPLEX GINZBURG–LANDAU EQUATION WITH LARGE THIRD-ORDER DISPERSION

open access: yesМоделирование и анализ информационных систем, 2015
We give an analytic proof of the existence of Shilnikov chaos in complex Ginzburg– Landau equation subject to a large third-order dispersion perturbation.

Modulation equations near the Eckhaus boundary: the KdV equation [PDF]

open access: yes, 2018
We are interested in the description of small modulations in time and space of wave-train solutions to the complex Ginzburg-Landau equation \begin{align*} \partial_T \Psi = (1+ i \alpha) \partial_X^2 \Psi + \Psi - (1+i \beta ) \Psi |\Psi|^2, \end{align*}

An equation for the limit state of a superconductor with pinning sites

open access: yesElectronic Journal of Differential Equations, 2005
We study the limit state of the inhomogeneous Ginzburg-Landau model as the Ginzburg-Landau parameter $kappa=1/epsilono infty$, and derive an equation to describe the limit state.

Homogenization of Attractors to Ginzburg-Landau Equations in Media with Locally Periodic Obstacles: Sub- and Supercritical Cases

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
The Ginzburg-Landau equation with rapidly oscillating terms in the equation and boundary conditions in a perforated domain was considered. Proof was given that the trajectory attractors of this equation converge weakly to the trajectory attractors of ...

Global Solvability of the Cauchy Problem for the Landau-Lifshitz-Gilbert Equation in Higher Dimensions

open access: yes, 2011
We prove existence, uniqueness and asymptotics of global smooth solutions for the Landau-Lifshitz-Gilbert equation in dimension $n \ge 3$, valid under a smallness condition of initial gradients in the $L^n$ norm.

Optical soliton solutions for time-fractional Ginzburg–Landau equation by a modified sub-equation method

open access: yesResults in Physics, 2023
In the present work, we employed a novel modification of the Sardar sub-equation approach, leading to the successful derivation of several exact solutions for the time-fractional Ginzburg–Landau equation with Kerr law nonlinearity.

Localized structures in coupled Ginzburg–Landau equations [PDF]

open access: yesPhysics Letters A, 2000
Coupled Complex Ginzburg-Landau equations describe generic features of the dynamics of coupled fields when they are close to a Hopf bifurcation leading to nonlinear oscillations. We study numerically this set of equations and find, within a particular range of parameters, the presence of uniformly propagating localized objects behaving as coherent ...

Coexisting Pulses in a Model for Binary-Mixture Convection

open access: yes, 1995
We address the striking coexistence of localized waves (`pulses') of different lengths which was observed in recent experiments and full numerical simulations of binary-mixture convection.
