15 Feb 2007 | Online Presentations | Contributor(s): Heng Li

The particle in a box (or the infinite potential well) is a simple idealized system that is completely solved within quantun mechanics. The infinite potential well is a finite sized region in space (the box) with an infinite potential at its boundaries ( the wells). A particle experiences no...

Simple Harmonic Oscillator

0.0 out of 5 stars

One of the most important model systems in quantum mechanics because a wide variaty of physical situations can be reduced to it either exactly or approximately. In particular, a system near an equilibrium configuration can often be described in terms of one or more harmonic oscillators....

Energy Bands In Periodic Potentials

It is the Kronig-Penny Model.The particle in one-dimensional lattice is a problem that occurs in the model of periodic crystal lattice.The potential is caused by periodic arrangement of ions in the crystal structure. The graph presents the real part of transmission matrix element P11 plotted...
