The spectrum of Schrödinger operators with Poisson type random potential (Q818912)

The authors show that, under wide conditions, the spectrum of Schrödinger operators is either the real axis or the semi positive real axis. The key of the proof is to use a representation of the spectrum by using a family of admissible potentials combined in some arguments in [\textit{W. Kirsch} and \textit{F. Martinelli}, Commun. Math. Phys. 85, 329--350 (1982; Zbl 0506.60058)].
