The ground state energy of the two dimensional Ginzburg–Landau functional with variable magnetic field

Abstract: Abstract. We consider the Ginzburg-Landau functional with a variable applied magnetic field in a bounded and smooth two dimensional domain. We determine an accurate asymptotic formula for the minimizing energy when the Ginzburg-Landau parameter and the magnetic field are large and of the same order. As a consequence, it is shown how bulk superconductivity decreases in average as the applied magnetic field increases.

“…As such, the assumption on the magnetic field in Theorem 1.1 is significant when b(κ)κ ≤ H ≤ M κ 2 and M ∈ (0, c 0 ] is a constant. Note also that our theorem gives a bridge between the situations studied by Attar in [1,2] and Pan-Kwek in [20]. Remark 1.4.…”

“…The case of a vanishing exterior magnetic field. We now discuss the case when B 0 vanishes along a curve, first considered in [20] and then in [1]. We assume that Similarly, at every point x of B −1 0 (0) ∩ ∂Ω, a toy operator is defined on R 2 + parameterized (up to unitary equivalence) by the intensity of B 0 (x) and the angle θ(x) ∈ [0, π/2) between the unit normal of the boundary and ∇B 0 (x).…”
