Breaking a magnetic zero locus: Asymptotic analysis

Abstract: This paper deals with the spectral analysis of the Laplacian in the presence of a magnetic field vanishing along a broken line. Denoting by θ the breaking angle, we prove complete asymptotic expansions of all the lowest eigenpairs when θ goes to 0. The investigation strongly uses a coherent state decomposition and a microlocal analysis of the eigenfunctions.
