In this chapter we study the regular solutions of the differential equations of quantum mechanics for the free particle, the particle in different boxes, the linear harmonic oscillator, atomic and molecular one-electron systems, the hydrogen atom in a static electric field, and the Stark effect for the hydrogen …
The quantum linear harmonic oscillator is one of the most fundamental applications of quantum mechanics to the real world Coherent states of the harmonic oscillator In these notes I will assume knowledge about the operator method for the harmonic oscillator corresponding to sect. 2.3 i "Modern Quantum Mechanics"
