Classical Physics as a Limit of Quantum Mechanics

The aim of this work was to analyze the quantum-mechanical time development of a wave packet in different simple potentials.  In special we tried  to find the the quasi classical behavior of the system and of the expectations values as limit from the quantum-mechanical description. This is possible, since classical physics must be contained as a limit in quantum mechanics.

The potentials were the one dimensional harmonic oscillator, the infinitely deep potential well and in the lecture is also a first attempt for the potential of the hydrogen atom. The used methods were analytic mathematics, formula manipulation and visualization with Mathematica and numeric integration and programming with FORTRAN.
