Microscopic derivation of Ginzburg-Landau theories for hierarchical quantum Hall states

open access: yesSciPost Physics, 2020
We propose a Ginzburg-Landau theory for a large and important part of the abelian quantum Hall hierarchy, including the prominently observed Jain sequences.

A comparison of Landau-Ginzburg models for odd-dimensional Quadrics [PDF]

open access: yes, 2018
In [Rie08], the second author defined a Landau-Ginzburg model for homogeneous spaces G/P, as a regular function on an affine subvariety of the Langlands dual group.

A geometric Ginzburg–Landau problem [PDF]

open access: yesMathematische Zeitschrift, 2012
Let \(M\) be a closed surface smoothly embedded in \(\mathbb R^3\). If \(\nu\) is its normal vector, \(A\) is its second fundamental form, and \({\mathcal H}^n\) is the \(n\)-dimensional Hausdorff measure, then for \(\varepsilon > 0\), the integral \[ E_\varepsilon(M)=\frac{\sqrt\varepsilon}2\int\limits_M\left(|A|^2+\frac{\nu_1^2}{\varepsilon^2}\right ...

Curl-free Ginzburg–Landau vortices [PDF]

open access: yesNonlinear Analysis: Theory, Methods & Applications, 1999
For certain nonlinear elliptic PDE problems in two dimensions, the classical isoperimetric inequality produces a sharp inequality that violates a Pohozaev identity except for radial symmetric, decreasing solutions. A generalized version of this technique is used here to prove radial symmetry of curl-free Ginzburg-Landau vortices.

Controllability of the Ginzburg–Landau equation

open access: yesComptes Rendus. Mathématique, 2007
This Note investigates the boundary controllability, as well as the internal controllability, of the complex Ginzburg–Landau equation. Null-controllability results are derived from a Carleman estimate and an analysis based upon the theory of sectorial operators.

THE GINZBURG–LANDAU EQUATION IN THE HEISENBERG GROUP [PDF]

open access: yesCommunications in Contemporary Mathematics, 2008
We consider a functional related with phase transition models in the Heisenberg group framework. We prove that level sets of local minimizers satisfy some density estimates, that is, they behave as "codimension one" sets. We thus deduce a uniform convergence property of these level sets to interfaces with minimal area.These results are then applied in ...

Solution Theory of Ginzburg-Landau Theory on BCS-BEC Crossover

open access: yesAdvances in Mathematical Physics, 2014
We establish strong solution theory of time-dependent Ginzburg-Landau (TDGL) systems on BCS-BEC crossover. By the properties of Besov, Sobolev spaces, and Fourier functions and the method of bootstrapping argument, we deduce that the global existence of ...

Landau-Ginzburg skeletons

open access: yesJournal of High Energy Physics, 2017
We study the class of indecomposable two-dimensional Landau-Ginzburg theories with (2,2) supersymmetry and central charge c < 6 with the aim of classifying all such theories up to marginal deformations.

The energy of Ginzburg–Landau vortices

open access: yesEuropean Journal of Applied Mathematics, 2002
We consider the Ginzburg–Landau equation in dimension two. We introduce a key notion of the vortex (interaction) energy. It is defined by minimizing the renormalized Ginzburg–Landau (free) energy functional over functions with a given set of zeros of given local indices.

Ginzburg–Landau equations and their generalizations

open access: yesIndagationes Mathematicae, 2023
The Ginzburg-Landau equations were proposed in the superconductivity theory to describe mathematically the intermediate state of superconductors in which the normal conductivity is mixed with the superconductivity. It was understood later on that these equations play an important role also in various problems of mathematical physics.
