Global Jacobian and Γ-convergence in a two-dimensional Ginzburg-Landau model for boundary vortices

نویسندگان

چکیده

In the theory of 2 D Ginzburg-Landau vortices, Jacobian plays a crucial role for detection topological singularities. We introduce related distributional quantity, called global that can detect both interior and boundary vortices map u . point out several features Jacobian, in particular, we prove an important stability property. This property allows us to study model arising thin ferromagnetic films, where weak anchoring energy penalising normal component at competes with usual bulk potential energy. asymptotic expansion by Γ-convergence second order this mixed boundary/interior regime are preferred. More precisely, first limiting expansion, is quantised determined number detected while term accounts interaction between vortices.

Γ-convergence of Graph Ginzburg–landau Functionals

We study Γ-convergence of graph-based Ginzburg–Landau functionals, both the limit for zero diffusive interface parameter ε → 0 and the limit for infinite nodes in the graph m→∞. For general graphs we prove that in the limit ε → 0 the graph cut objective function is recovered. We show that the continuum limit of this objective function on 4-regular graphs is related to the total variation semino...

Γ-convergence of the Ginzburg-landau Energy

From elliptic regularity one immediately has that, should such a minimizer u exist, u ∈ C∞(Ω̄). Then u is in fact a smooth (analytic, even) harmonic function obtaining the boundary value g, i.e. a solution to the classical Dirichlet problem with boundary data g. A standard exercise in the Direct Method of the Calculus of Variations provides for the existence of a minimizer, i.e. ∃u ∈ H g (Ω;R) s...

Renormalized Ginzburg-Landau energy and location of near boundary vortices

We consider the location of near boundary vortices which arise in the study of minimizing sequences of Ginzburg-Landau functional with degree boundary condition. As the problem is not well-posed — minimizers do not exist, we consider a regularized problem which corresponds physically to the presence of a superconducting layer at the boundary. The study of this formulation in which minimizers no...

On compound vortices in a two-component Ginzburg-Landau functional

We study the structure of vortex solutions in a Ginzburg–Landau system for two complex valued order parameters. We consider the Dirichlet problem in the disk in R2 with symmetric, degree-one boundary condition, as well as the associated degree-one entire solutions in all of R2. Each problem has degree-one equivariant solutions with radially symmetric profile vanishing at the origin, of the same...
