Asymmetry of the Ferroelectric Phase Transition in BaTiO3

Advanced Materials, Volume 38, Issue 25, 4 May 2026.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

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

Triggered Ferroelectricity in HfO2 From Hybrid Phonons and Higher‐Order Dynamical Charges

Advanced Materials, Volume 38, Issue 19, 1 April 2026.
We combine first‐principles calculations, LGD theory and group theory to demonstrate the mechanism of hybrid‐triggered ferroelectricity in HfO2${\rm HfO}_2$, enabled by trilinear and quadlinear couplings between stable polar and nonpolar modes. HfO2${\rm HfO}_2$ hosts unconventional interplay between structure modes where substantial contribution to ...

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.

The Hopf bifurcation and spiral wave solution of the complex Ginzburg-Landau equation

, 2002
When the dispersive and diffusive effects are negligible, the complex Ginzburg-Landau equation degenerates, in form, as the Landau equation, in which occurs the Hopf bifurcation.

Defect chaos and bursts: Hexagonal rotating convection and the complex Ginzburg-Landau equation [PDF]

, 2006
We employ numerical computations of the full Navier-Stokes equations to investigate non-Boussinesq convection in a rotating system using water as the working fluid. We identify two regimes.

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.

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 ...

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
