Nonlinear Magnetoconvection in a Sparsely Packed Porous Medium

International Journal of Geophysics, 2011
Linear and weakly nonlinear properties of magnetoconvection in a sparsely packed porous medium are investigated. We have obtained the values of Takens-Bogdanov bifurcation points and codimension two bifurcation points by plotting graphs of neutral curves

Decoding Superconductivity in La3Ni2O7−δ Thin Films via Ozone‐Driven Structure and Oxidation Tuning

Small Structures, Volume 7, Issue 8, August 2026.
We demonstrate that superconductivity in La3Ni2O7‐δ thin films correlate with the LNO‐2222 polytype, which must extend coherently across the layer. Conversely, the LNO‐1313 phase disrupts superconductivity, as confirmed by recent studies. Our work highlights the need to stabilize the 2222 phase through optimized growth to achieve robust and ...

On the Analyticity for the Generalized Quadratic Derivative Complex Ginzburg-Landau Equation

Abstract and Applied Analysis, 2014
We study the analytic property of the (generalized) quadratic derivative Ginzburg-Landau equation (1/2⩽α⩽1) in any spatial dimension n⩾1 with rough initial data.

Mesoscale Domain Evolution Mechanism during Alternating Current (AC) Poling of Relaxor Ferroelectrics

Advanced Functional Materials, Volume 36, Issue 56, 13 July 2026.
Ferroelectric domain variants that are energetically equivalent are expected to remain preserved during polarization reversal. However, phase‐field simulations reveal that inclined domain walls in relaxor ferroelectrics can undergo irreversible elimination during alternating current poling through a proximity effect driven by long‐range elastic ...

On the stable hole solutions in the complex Ginzburg–Landau equation

Physica A: Statistical Mechanics and its Applications, 2005
Abstract We show numerically that the one-dimensional quintic complex Ginzburg–Landau equation admits four different types of stable hole solutions. We present a simple analytic method which permits to calculate the region of existence and approximate shape of stable hole solutions in this equation.

Ferroelectric Dynamic‐Field‐Driven Nucleation and Growth Model for Predictive Materials‐To‐Circuit Co‐Design

Advanced Materials, Volume 38, Issue 40, 17 July 2026.
This study presents a compact dynamic‐field‐driven nucleation and growth (DFNG) model that captures ferroelectric switching behavior under arbitrary voltage waveforms. It enables extraction of time‐dependent domain wall velocity and growth dimensionality, which can then be extended to device‐level modeling.

Bifurcations, chaotic behavior, and optical solutions for the complex Ginzburg–Landau equation

Results in Physics
This research focuses on investigating an extended version of the Ginzburg–Landau (GL) equation that describes the motion of particles in a plasma. The other applications of this model can be found in optics, and other related fields.

Blow-up profile for the complex Ginzburg–Landau equation

Journal of Functional Analysis, 2008
This paper deals with the study of the Ginzburg-Landau equation \[ u_t=(1+i\beta )\Delta u+(1+i\delta )| u| ^{p-1}u-\gamma u, \quad u(\cdot ,0)\in L^\infty ({\mathbb R}^N,{\mathbb C}), \] where \(p>1\) and the constants \(\beta\), \(\delta\) and \(\gamma\) are real. The authors construct a solution \(u(x,t)\) that blows up in some finite time \(T\), in

Numerical Investigation of the Dynamics of ‘Hot Spots’ as Models of Dissipative Rogue Waves

Applied Sciences, 2018
In this paper, the effect of gain or loss on the dynamics of rogue waves is investigated by using the complex Ginzburg-Landau equation as a framework. Several external energy input mechanisms are studied, namely, constant background or compact Gaussian ...
