Study of heat and mass transport in Couple-Stress liquid under G-jitter effect

Ain Shams Engineering Journal, 2018
In the present paper, we deal with the effect of G-jitter (time periodic gravity modulation) on the stability of double diffusive convection in couple stress liquid by method of non-linear analysis. The infinitesimal disturbances are expanded in terms of

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering

Advanced Science, Volume 13, Issue 25, 4 May 2026.
This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Das Ginzburg-Landau Paradigma

, 2017
In this thesis we establish a functional approach to prove the existence of Ginzburg-Landau spiral waves. Based on systematic considerations, we justify the popular m-armed spiral Ansatz by equivariance and the variational structure of the real Ginzburg ...

Towards Ginzburg–Landau Bogomolny Approach and a Perturbative Description of Superconducting Structures

Quantum Reports
The Bogomolny approach to the Ginzburg–Landau equations in the context of strong and semi-strong necessary conditions is formulated for various superconducting structures in a quasi-one-dimensional description, considering both flat and curved geometries.

Pullback attractors for the non-autonomous complex Ginzburg–Landau type equation with p-Laplacian

Nonlinear Analysis, 2015
In this paper, we are concerned with the long-time behavior of the non-autonomous complex Ginzburg–Landau type equation with p-Laplacian. We first prove the existence of pullback absorbing sets in L2(Ω)∩W01,p(Ω)∩Lq(Ω) for the process {U(t,τ)}t⩾τ ...

Supersymmetric Landau-Ginzburg tensor models

Journal of High Energy Physics, 2019
We study two dimensional N $$ \mathcal{N} $$ = (2, 2) Landau-Ginzburg models with tensor valued superfields with the aim of constructing large central charge superconformal field theories which are solvable using large N techniques.

On the theory of current states in superconducting junctions of SNINS type

Condensed Matter Physics, 2006
The behavior of the order parameter close to the NS interface in an SNINS junction is considered. To this end, a linear integral equation, which is valid near the superconductor-normal metal interface, is obtained and researched.
