Quantum mechanics: some basic techniques for some basic models, I: The models

Vincenzo Grecchi

Vol. 4 (2016), No. 3-4, 335–352

Abstract

This is a short review of the main results on the oscillators considered basic models in quantum mechanics. Since the potential is polynomial, it is possible to extend the stationary states to entire functions on the complex plane where the semiclassical theory works better. The control on the energy levels is based on the isolation of the nodes, the zeros stable at the unperturbed limit. A new and simple model for the process of racemization of chiral molecules is added.
