Regularity and Qualitative Study of Parabolic Physical Ginzburg–Landau Equations in Variable Exponent Herz Spaces via Fractional Bessel–Riesz Operators

Fractal and Fractional
In this article, we investigate the regularization and qualitative properties of parabolic Ginzburg–Landau equations in variable exponent Herz spaces. These spaces capture both local and global behavior, providing a natural framework for our analysis. We

A Fourth Order Energy Dissipative Scheme for a Traffic Flow Model

Mathematics, 2020
We propose, analyze and numerically validate a new energy dissipative scheme for the Ginzburg–Landau equation by using the invariant energy quadratization approach.

Electrically and Magnetically Tunable Charge–Density–Wave Transport in Quasi‐2D h‐BN/1T‐TaS2 Field Effect Devices

Advanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
Perpendicular electric and magnetic fields are used to control charge‐density‐wave (CDW) domain dynamics in quasi‐two‐dimensional h‐BN/1T‐TaS2 field‐effect devices. Electrical gating produces a non‐monotonic modulation of the CDW depinning threshold — behavior distinct from quasi‐one‐dimensional CDW systems.

Abelian reductions of deformed N=4 SYM

Nuclear Physics B, 2015
Following the work in [1], where the massive ABJM model in 2+1 dimensions was shown to have an abelian reduction to the relativistic Landau–Ginzburg, and motivated by the implications for condensed matter through AdS/CFT, we show that a FI deformation of

Modeling small‐angle scattering data of porous and/or bicontinuous structures in n dimensions

Journal of Applied Crystallography, Volume 59, Issue 3, Page 837-844, June 2026.
A small‐angle scattering fitting function is derived for porous materials with arbitrary fractal dimension. It includes a correlation peak and a power law at higher q.Fractal structures are often observed in small‐angle scattering experiments where a simple power law q−α describes the scattering intensity over many orders of magnitude.

Irreducible Ginzburg-Landau fields in dimension 2

, 2018
Ginzburg--Landau fields are the solutions of the Ginzburg--Landau equations which depend on two positive parameters, $\alpha$ and $\beta$. We give conditions on $\alpha$ and $\beta$ for the existence of irreducible solutions of these equations.

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.

On a Cubic-Quintic Ginzburg-Landau Equation with Global Coupling

, 2005
We study standing wave solutions in a Ginzburg-Landau equation which consists of a cubic-quintic equation stabilized by global coupling A_t= \Delta A +\mu A + c A^3 -A^5 -k A (\int_{R^n} A^2\,dx).

Global existence via Ginzburg-Landau formalism and pseudo- orbits of Ginzburg-Landau approximations [PDF]

, 2014
The so-called Ginzburg-Landau formalism applies for parabolic systems which are defined on cylindrical domains, which are close to the threshold of instability, and for which the unstable Fourier modes belong to non-zero wave numbers.
