Hole Structures in Nonlocally Coupled Noisy Phase Oscillators

open access: yes, 2007
We demonstrate that a system of nonlocally coupled noisy phase oscillators can collectively exhibit a hole structure, which manifests itself in the spatial phase distribution of the oscillators.

Advancing superconductivity research: Insights from numerical simulations of potassium fullerenide-60 and gold and with Ginzburg-Landau theory

open access: yesResults in Materials
There are many types of superconductors, including gold ormus and some fullerene derivatives. Gold can become a superconductor at extremely low temperatures (

A Liouville theorem for the fractional Ginzburg–Landau equation

open access: yesComptes Rendus. Mathématique, 2020
In this paper, we are concerned with a Liouville-type result of the nonlinear integral equation \begin{equation*} u(x)=\int _{\mathbb{R}^{n}}\frac{u(1-|u|^{2})}{|x-y|^{n-\alpha }}\mathrm{d}y, \end{equation*} where $u: \mathbb{R}^{n} \rightarrow \mathbb{

Testing the Ginzburg-Landau approximation for three-flavor crystalline color superconductivity

open access: yes, 2006
It is an open challenge to analyze the crystalline color superconducting phases that may arise in cold dense, but not asymptotically dense, three-flavor quark matter.

Topological methods for the Ginzburg-Landau equations

open access: yesJournal de Mathématiques Pures et Appliquées, 1998
Summary: We consider the Ginzburg-Landau equation \[ - \Delta u = \varepsilon^{- 2} u \bigl( 1 - |u |^2 \bigr) \text{ in } \Omega, \quad u = g \text{ on } \partial \Omega, \] where \(\Omega\) is a domain in \(\mathbb{R}^2\), \(g : \partial \Omega \to \mathbb{C}\) is such that \(|g |= 1\) on \(\partial \Omega\), and \(\varepsilon > 0\) is a parameter ...

Weakly Nonlinear Magnetic Convection in a Nonuniformly Rotating Electrically Conductive Medium Under the Action of Modulation of External Fields

open access: yesEast European Journal of Physics, 2020
In this paper we studied the weakly nonlinear stage of stationary convective instability in a nonuniformly rotating layer of an electrically conductive fluid in an axial uniform magnetic field under the influence of: a) temperature modulation of the ...

Quantization effects for multi-component Ginzburg-Landau vortices

open access: yesAdvanced 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 ...

Bifurcations of Nonconstant Solutions of the Ginzburg-Landau Equation

open access: yesAbstract and Applied Analysis, 2012
We study local and global bifurcations of nonconstant solutions of the Ginzburg-Landau equation from the families of constant ones. As the topological tools we use the equivariant Conley index and the degree for equivariant gradient maps.

Uniqueness of the Invariant Measure for a Stochastic PDE Driven by Degenerate Noise

open access: yes, 2000
We consider the stochastic Ginzburg-Landau equation in a bounded domain. We assume the stochastic forcing acts only on high spatial frequencies. The low-lying frequencies are then only connected to this forcing through the non-linear (cubic) term of the ...

Theoretical Study of Upper Critical Magnetic Field (HC2) in Multiband Iron Based Superconductors

open access: yesAdvances in Condensed Matter Physics, 2016
This research work focuses on the theoretical investigation of the upper critical magnetic field, HC2; Ginzburg-Landau coherence length, ξGL(T); and Ginzburg-Landau penetration depth, λGL(T), for the two-band iron based superconductors BaFe2(As1-xPx)2 ...
