Fibers over infinity of Landau-Ginzburg models
, 2022 We conjecture that the number of components of the fiber over infinity of Landau--Ginzburg model for a smooth Fano variety $X$ equals the dimension of the anticanonical system of $X$.

Semistable degenerations of Calabi–Yau manifolds and mirror P=W conjectures
Forum of Mathematics, SigmaMirror symmetry for a semistable degeneration of a Calabi–Yau manifold was first investigated by Doran–Harder–Thompson when the degenerate fiber is a union of two quasi-Fano manifolds.

Advanced Materials, EarlyView.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.

On the Lawrence–Doniach and Anisotropic Ginzburg–Landau Models for Layered Superconductors
, 1995 The authors consider two models, the Lawrence-Doniach and the anisotropic Ginzburg-Landau models for layered superconductors such as the recently discovered high-temperature superconductors.

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials
Advanced Materials Interfaces, EarlyView.Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

An equation for the limit state of a superconductor with pinning sites
Electronic Journal of Differential Equations, 2005 We study the limit state of the inhomogeneous Ginzburg-Landau model as the Ginzburg-Landau parameter $kappa=1/epsilono infty$, and derive an equation to describe the limit state.

Advanced Science, EarlyView.Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Fenómeno de transporte en superconductores: vórtices cinemáticos
Iteckne, 2017 La teoría fenomenológica Ginzburg-Landau (FGLT) es una fuerte herramienta para entender la física de los materiales superconductores a temperaturas críticas en presencia de campos magnéticos y corrientes aplicadas.

Advanced Science, EarlyView.Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...

, 1994 We investigate a class of (2,2) supersymmetric string vacua which may be represented as Landau--Ginzburg theories with a quasihomogeneous potential which has an isolated singularity at the origin. There are at least three thousand distinct models in this
