Abstract
We consider a Schrödinger operator ( hD − A )^2 with a positive magnetic field B = curlA in a domain Ω ⊂ ℝ^2 . The imposing of Neumann boundary conditions leads to the existence of some spectrum below h ∈ f B . This is a boundary effect and it is related to the existence of edge states of the system. We show that the number of these eigenvalues, in the semi-classical limit h → 0, is governed by a Weyl-type law and that it involves a symbol on ∂Ω. In the particular case of a constant magnetic field, the curvature plays a major role.
