Low-Magnetic Field Critical Behavior in Strongly Type-II Superconductors

, 1995
A new description is proposed for the low-field critical behavior of type-II superconductors. The starting point is the Ginzburg-Landau theory in presence of an external magnetic field H.

Order of superconductive phase transition

Condensed Matter Physics, 2005
On the occasion of Reinhard Folk's 60th birthday, I give a brief review of the theoretical progress in understanding the critical properties of superconductors. I point out the theoretical difficulties in finding a second-order transition in the Ginzburg-

Higher-matter and Landau-Ginzburg theory of higher-group symmetries

SciPost Physics
Higher-matter is defined by higher-representation of a symmetry algebra, such as the $p$-form symmetries, higher-group symmetries or higher-categorical symmetries.

Damped nonlinear Ginzburg-Landau equation with saturation. Part I. Existence of solutions on general domains [PDF]

Opuscula Mathematica
We study the complex Ginzburg-Landau equation posed on possibly unbounded domains, including some singular and saturated nonlinear damping terms. This model interpolates between the nonlinear Schrödinger equation and dissipative parabolic dynamics ...

Schauder-Tychonoff Fixed-Point Theorem in Theory of Superconductivity

Journal of Function Spaces and Applications, 2013
We study the existence of mild solutions to the time-dependent Ginzburg-Landau ((TDGL), for short) equations on an unbounded interval. The rapidity of the growth of those solutions is characterized.

Single-Defect-Induced Peculiarities in Inverse Faraday-Based Switching of Superconducting Current-Carrying States near a Critical Temperature

Condensed Matter
The Inverse Faraday Effect (IFE) is a phenomenon that enables non-thermal magnetization in various types of materials through the interaction with circularly polarized light.

Fragmented superconductivity in the Hubbard model as solitons in Ginzburg–Landau theory

npj Quantum Materials
The phenomena of superconductivity and charge density waves are observed in close vicinity in many strongly correlated materials. Increasing evidence from experiments and numerical simulations suggests both phenomena can also occur in an intertwined ...

Fully stabilized Minkowski vacua in the 26 Landau-Ginzburg model

Journal of High Energy Physics
We study moduli stabilization via fluxes in the 26 Landau-Ginzburg model. Fluxes not only give masses to scalar fields but can also induce higher order couplings that stabilize massless fields.

Control-translated Finsler-type structure and anisotropic Ginzburg-Landau models

Nuclear Physics B
This paper develops a geometric and analytical extension of the Finsler-Ginzburg-Landau framework by introducing a distributed control field acting as a translation in the tangent bundle.

Superconducting film in the external periodic magnetic field

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
The elementary model of the superconducting state of a thin film in the nonuniform external magnetic field is developed. In the diffusive limit of the superconductivity microscopic theory, the problem of the critical amplitude of the periodic external ...
