Operators and Dynamical Variables
In the last chapters we dealt with solvable one-dimensional systems described by the stationary Schrödinger equation. In the solutions of these systems we had a first approach to the quantum phenomena. We found that for systems with confining potentials the physical variables generally quantize. For some of this kind of systems, we could determine the momentum and energy eigenvalues as well as their corresponding eigenfunctions. We found also the tunneling effect, the energy levels splitting and we were able to evaluate the particle current density and the reflection and transmission coefficients.
