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

open access: yesOpuscula 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 ...

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

open access: yesCondensed 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.

Schauder-Tychonoff Fixed-Point Theorem in Theory of Superconductivity

open access: yesJournal 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.

Modeling ternary mixtures by mean-field theory of polyelectrolytes: Coupled Ginzburg–Landau and Swift–Hohenberg equations [PDF]

open access: yes, 2012
The purpose of this work is to model ternary mixtures using the theory of pattern formation and of polyelectrolytes, with mean-field approximations. The model has two local, non-conserved order parameters.

Microscopic Derivation of Ginzburg-Landau Theory [PDF]

open access: yes, 2012
We give the first rigorous derivation of the celebrated Ginzburg-Landau (GL) theory, starting from the microscopic Bardeen-Cooper-Schrieffer (BCS) model. Close to the critical temperature, GL arises as an effective theory on the macroscopic scale.

Different length scales for order parameters in two-gap superconductors : extended Ginzburg-Landau theory

open access: yes, 2011
: Using the Ginzburg-Landau theory extended to the next-to-leading order, we determine numerically the healing lengths of the two order parameters at the two-gap superconductor/normal metal interface.

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

open access: yesnpj 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 ...

A Phenomenological Effective-Field Theory for a Charged Spin-1 Condensate in Anisotropic Layered Superconductors

open access: yesPhyschem
We formulate a gauge-invariant phenomenological theory for a charged three-component condensate in an anisotropic layered superconductor. The construction is conditional on a material-specific pairing calculation selecting an isolated, predominantly ...

A Landau-Ginzburg/Calabi-Yau Correspondence for the Mirror Quintic. [PDF]

open access: yes
From High Energy Physics there is a certain expected correspondence between two different physical models, the Landau--Ginzburg model and the geometric or Calabi--Yau model. This correspondence is known as the Landau--Ginzburg/Calabi--Yau correspondence.

Fully stabilized Minkowski vacua in the 26 Landau-Ginzburg model

open access: yesJournal 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.
