The improved Ginzburg-Landau technique

EPJ Web of Conferences, 2018
We discuss an innovative method for the description of inhomogeneous phases designed to improve the standard Ginzburg-Landau expansion. The method is characterized by two key ingredients.

Witten Deformation on noncompact manifolds and Landau-Ginzburg B-model [PDF]

, 2022
Motivated by the Calabi-Yau/Landau-Ginzburg correspondence, we study BCOV-type torsion for Landau-Ginzburg B-models. To pave the way for understanding the Landau-Ginzburg model from the index theoretic point of view, we study Witten deformation, which ...

Instability of Ginzburg-Landau Vortices on Manifolds

, 2013
We investigate two settings of Ginzburg-Landau posed on a manifold where vortices are unstable. The first is an instability result for critical points with vortices of the Ginzburg-Landau energy posed on a simply connected, compact, closed 2-manifold ...

Ginzburg-Landau-Theorie für Bosonen in optischen Gittern

, 2011
In this thesis the quantum phase transition of spinless bosons in optical lattices is described within a Ginzburg-Landau theory. To this end the underlying effective action is derived from the microscopic Bose-Hubbard Hamiltonian by developing ...

Partial compactness for the 2-D Landau-Lifshitz flow

Electronic Journal of Differential Equations, 2004
Uniform local $C^infty$-bounds for Ginzburg-Landau type approximations for the Landau-Lifshitz flow on planar domains are proven. They hold outside an energy-concentration set of locally finite parabolic Hausdorff-dimension 2, which has finite ...

Ginzburg-Landau Model for Stability Analysis of Fluid Flows

A general scheme for the solution of stability problems for two-dimensional flows (the Navier-Stokes equations and shallow water equations) by means of a weakly nonlinear theory is analyzed in the paper. Equations of the first, second and the third order
