Absence of positive eigenvalues of magnetic Schroedinger operators

We study sufficient conditions for the absence of positive eigenvalues of magnetic Schroedinger operators in $\mathbb{R}^n$. In our main result we prove the absence of eigenvalues above certain threshold energy which depends explicitly on the magnetic and electric field. A comparison with the examples of Miller-Simon shows that our result is sharp as far as the decay of the magnetic field is concerned.

The talk is based on a joint work with Silvana Avramska-Lukarska and Dirk Hundertmark.
