Curl-free Ginzburg–Landau vortices [PDF]

Nonlinear 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.

Discrete Ginzburg-Landau Solitons

Physical Review E, 2003
We demonstrate that discrete solitons are possible in Ginzburg-Landau lattices. As a result of discreteness, we find that this system exhibits a host of features that have no counterpart whatsoever in either the continuous limit or in other conservative discrete models.

Solitons and Jacobi Elliptic Function Solutions to the Complex Ginzburg–Landau Equation

Frontiers in Physics, 2020
The complex Ginzburg–Landau (CGL) equation which describes the soliton propagation in the presence of the detuning factor is firstly considered; then its solitons as well as Jacobi elliptic function solutions are obtained systematically using a modified ...

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

SciPost 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.

Finsler geometry in anisotropic superconductivity: a Ginzburg-Landau approach [PDF]

Open Communications in Nonlinear Mathematical Physics
We present a rigorous generalization of the classical Ginzburg--Landau model to smooth, compact Finsler manifolds without boundary. This framework provides a natural analytic setting for describing anisotropic superconductivity within Finsler geometry ...

Temperature-Dependent Ginzburg–Landau Parameter [PDF]

Journal of the Physical Society of Japan, 2012
Taking into account both the orbital and the paramagnetic depairing effects we derive a simple analytic formula for the temperature dependence of the Ginzburg-Landau parameter valid in vicinity of field dependent critical temperature in a type-II superconductor.

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

Advances 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

Journal 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.
