Fractional Ginzburg–Landau equation for fractal media [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2005
We derive the fractional generalization of the Ginzburg-Landau equation from the variational Euler-Lagrange equation for fractal media. To describe fractal media we use the fractional integrals considered as approximations of integrals on fractals. Some simple solutions of the Ginzburg-Landau equation for fractal media are considered and different ...

Nonstationary Superconductivity: Quantum Dissipation and Time-Dependent Ginzburg-Landau Equation

open access: yesAdvances in Condensed Matter Physics, 2011
Transport equations of the macroscopic superfluid dynamics are revised on the basis of a combination of the conventional (stationary) Ginzburg-Landau equation and Schrödinger's equation for the macroscopic wave function (often called the order parameter)

Conservative Finite-Difference Scheme for 1D Ginzburg–Landau Equation

open access: yesMathematics, 2022
In this study, our attention is focused on deriving integrals of motion (conservation laws; invariants) for the problem of an optical pulse propagation in an optical fiber containing an optical amplifier or attenuator because, to date, such invariants ...

Ginzburg-Landau theory of a trapped Fermi gas with a BEC-BCS crossover

open access: yes, 2009
The Ginzburg-Landau theory of a trapped Fermi gas with a BEC-BCS crossover is derived by the path-integral method. In addition to the standard Ginzburg-Landau equation, a second equation describing the total atom density is obtained.

Complex Ginzburg-Landau equation with nonlocal coupling [PDF]

open access: yesPhysical Review E, 2003
A Ginzburg-Landau-type equation with nonlocal coupling is derived systematically as a reduced form of a universal class of reaction-diffusion systems near the Hopf bifurcation point and in the presence of another small parameter. The reaction-diffusion systems to be reduced are such that the chemical components constituting local oscillators are ...
