Mathematical Methods in Quantum Mechanics
With Applications to Schrödinger Operators
Gerald Teschl
The second part starts with a detailed study of the free Schrödinger operator respectively position, momentum and angular momentum operators. Then we develop WeylTitchmarsh theory for SturmLiouville operators and apply it to spherically symmetric problems, in particular to the hydrogen atom. Next we investigate selfadjointness of atomic Schrödinger operators and their essential spectrum, in particular the HVZ theorem. Finally we have a look at scattering theory and prove asymptotic completeness in the short range case.
