100 anos de supercondutividade e a teoria de Ginzburg-Landau

Revista Brasileira de Ensino de Física
Este artigo é uma proposta de ensino de supercondutividade para estudantes de nível de graduação na área de ciências exatas. Utilizando a formulação fenomenológica de Ginzburg-Landau do fenômeno, pretendemos dar uma contribuição para o aprendizado deste ...

A theory of giant vortices

Journal of High Energy Physics, 2021
We elaborate a theory of giant vortices [1] based on an asymptotic expansion in inverse powers of their winding number n. The theory is applied to the analysis of vortex solutions in the abelian Higgs (Ginzburg-Landau) model.

Matrix Factorizations, D-Branes and their Deformations [PDF]

, 2007
We review in elementary, non-technical terms the description of topological B-type of D-branes in terms of boundary Landau-Ginzburg theory, as well as some applications.Comment: 20p, 5 figs, Proceedings of Cargese school on string theory ...

Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article reviews the fundamental consequences of strong correlations on excitations and elementary steps of energy conversion leading to new opportunities to control energy conversion. Examples include friction at surfaces, thermal transport, and photovoltaic energy conversion.

Gravitating Electron Based on Overrotating Kerr-Newman Solution

Universe, 2022
We consider a consistent with gravity electron based on the overrotating Kerr-Newman (KH) solution and show that the earlier KH electron models proposed by Carter, Israel and López in 1970–1990 should be modified by the Landau-Ginzburg theory, leading to

Ginzburg-Landau-type theory of non-polarized spin superconductivity

, 2017
Since the concept of spin superconductor was proposed, all the related studies concentrate on spin-polarized case. Here, we generalize the study to spin-non-polarized case.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Fixed points of (0,2) Landau-Ginzburg renormalization group flows and the chiral algebra

Journal of High Energy Physics, 2022
We discuss renormalization group flows in two-dimensional quantum field theories with (0,2) supersymmetry. We focus on theories with UV described by a Landau-Ginzburg Lagrangian and use the chiral algebra to constrain the IR dynamics. We present examples

Phenomenological correlations in high-temperature superconductors

, 2014
An interpretation of the quadratic parameter of the Ginzburg-Landau theory of superconductivity is presented in this paper. The negative term in the potential, which allows the spontaneous symmetry breaking, is interpreted as a direct contribution from ...
