Proximity Ferroelectricity in Compositionally Graded Structures

Advanced Electronic Materials, Volume 12, Issue 7, 6 April 2026.
We perform the finite element modeling of the polarization switching in the compositionally graded AlN‐Al1‐xScxN and ZnO‐Zn1‐xMgxO structures and reveal the switching of spontaneous polarization in the whole structure in all these systems. The coercive field to switch is significantly lower than the electric breakdown field of the unswitchable AlN and ...

The Effect of Modulation on Heat Transport by a Weakly Nonlinear Thermal Instability in the Presence of Applied Magnetic Field and Internal Heating

International Journal of Applied Mechanics and Engineering, 2020
The present paper deals with a weakly nonlinear stability problem under an imposed time-periodic thermal modulation. The temperature has two parts: a constant part and an externally imposed time-dependent part. We focus on stationary convection using the

Materials Design Principles for Large Memory Windows: Coercive Voltage Engineering in Ferroelectric– Dielectric Heterostructures

Advanced Electronic Materials, Volume 12, Issue 8, 20 April 2026.
Coercive voltage enhancement in hafnia‐based ferroelectric–dielectric heterostructures is shown to originate from leakage‐governed voltage division between the ferroelectric and dielectric layers. Through experiments, circuit modeling, and defect‐based simulations, a universal framework is established to engineer large memory windows without altering ...

A High-Precision Numerical Method for the Fractional-in-Time Complex Ginzburg–Landau Equation with Periodic Boundary Condition

Fractal and Fractional
This paper investigates the chaotic and pattern dynamics of the time-fractional Ginzburg–Landau equation. First, we propose a high-precision numerical method that combines finite difference schemes with an improved Grünwald–Letnikov fractional derivative

Optical solitons with differential group delay for complex Ginzburg–Landau equation

Results in Physics, 2020
This paper addresses optical solitons in birefringent fibers that is modeled by complex Ginzburg–Landau equation with Kerr law nonlinearity. Three forms of integration architecture retrieves soliton and other solutions to the model.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Enhanced Ferroelectricity in Hf1−XZrXO2 Thin Films Through Ultrathin Mo Electrode Layer and Microwave Annealing

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 4, April 2026.
Uniform volumetric heating via microwave annealing combined with an ultrathin Mo interlayer enables low‐temperature crystallization of thin HZO films. Interfacial degradation and dead‐layer formation are suppressed, resulting in enlarged ferroelectric domains, uniform switching behavior, and a high remanent polarization of 45.2 μC/cm2 at 200°C.

A Liouville theorem for the fractional Ginzburg–Landau equation

Comptes 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{

Quantization effects for multi-component Ginzburg-Landau vortices

Advanced 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 ...
