Abstract [en]

For a fixed magnetic quantum number m results on spectral properties and scattering theory are given for the three-dimensional Schrodinger operator with a constant magnetic field and an axisymmetrical electric potential V. Asymptotic expansions for the resolvent of the Hamiltonian H-m = H-om + V are deduced as the spectral parameter tends to the lowest Landau threshold E-0. In particular it is shown that E-0 can be an eigenvalue of H-m. Furthermore, asymptotic expansions of the scattering matrix associated with the pair (H-m, H-om) are derived as the energy parameter tends to E-0.
