Research Abstract

The spectrum of various quantum systems are analyzed. The main result of this research is the analysis of the quantum system of a charged particle interacting with a quantized radiation field. It is proved that the ionization energy of the system is strictly positive. Moreover, we made a study of the ergodicity and the Liouville's theorem for a quantum dynamics, the uniqueness or crossing property of eigenvalues of the non-commutative harmonic oscillators, spectral analysis of the discrete Schrodinger with rank one perturbation.
