Eigenvalues of the Neumann magnetic Laplacian in the semi-classical limit and analogies with Robin Laplacians

Nicolas Popoff
Date et heure
Workshop - Magnetic fields and semi-classical analysis

In this talk, I will describe results obtained in the last decade on the first eigenvalues of the Neumann magnetic Laplacian in the semi-classical limit, more particularly, I will show how the geometry of the situation (singularities of the boundary, curvature) influences the first order asymptotics, and also the spectral gap, under suitable assumptions. Then I will present recent results about eigenvalues of Robin Laplacian with strong Dirichlet boundary condition and show the analogies between these two operators.
