Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced 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.

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

open access: yes, 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.

Bridging Superconductors With United Nations Development Goals: Perspectives and Applications

open access: yesphysica status solidi (a), Volume 223, Issue 7, 7 April 2026.
Ceramic superconductors enable sustainable technologies. A bibliometric review of 33,756 publications (1980–2025) assesses their alignment with the UN Sustainable Development Goals. Key applications identified from include clean propulsion, efficient power grids, advanced medical imaging, and quantum computing, highlighting both their transformative ...

Meromorphic traveling wave solutions of the complex cubic-quintic Ginzburg-Landau equation [PDF]

open access: yes, 2012
We look for singlevalued solutions of the squared modulus M of the traveling wave reduction of the complex cubic-quintic Ginzburg-Landau equation. Using Clunie's lemma, we first prove that any meromorphic solution M is necessarily elliptic or degenerate ...

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

open access: yesAdvanced 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 ...

Standing waves of the complex Ginzburg-Landau equation

open access: yes, 2013
We prove the existence of nontrivial standing wave solutions of the complex Ginzburg-Landau equation $\phi_t = e^{i\theta} \Delta \phi + e^{i\gamma} |\phi |^\alpha \phi $ with periodic boundary conditions. Our result includes all values of $\theta $ and $

Hole Solutions in the 1d Complex Ginzburg-Landau Equation

open access: yes, 1994
The cubic Complex Ginzburg-Landau Equation (CGLE) has a one parameter family of traveling localized source solutions. These so called 'Nozaki-Bekki holes' are (dynamically) stable in some parameter range, but always structually unstable: A perturbation ...

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

open access: yesAdvanced 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 ...
