Quantum Mechanics: Harmonic Oscillator
Series | 09 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The quantum harmonic oscillator is the quantum mechanical analogue of the classical harmonic oscillator. It is one of the most important model systems in quantum mechanics because an arbitrary potential can be approximated as a harmonic potential at the vicinity of a stable equilibrium point....

Quantum Mechanics: WKB Approximation
Series | 09 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
In physics, the WKB (Wentzel–Kramers–Brillouin) approximation, also known as WKBJ (Wentzel–Kramers–Brillouin–Jeffreys) approximation, is the most familiar example of a semiclassical calculation in quantum mechanics in which the wavefunction is recast as an exponential function, semiclassically...

Quantum Mechanics: Hydrogen Atom and Electron Spin
Series | 09 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively-charged proton and a single negatively-charged electron bound to the nucleus by the Coulomb force. The most abundant isotope, hydrogen-1, protium, or light hydrogen, contains no...

Quantum Mechanics: The story of the electron spin
Teaching Materials | 09 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
One of the most remarkable discoveries associated with quantum physics is the fact that elementary particles can possess non-zero spin. Elementary particles are particles that cannot be divided into any smaller units, such as the photon, the electron, and the various quarks. Theoretical and...

Quantum Mechanics: Landauer's Formula
Series | 08 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
When a metallic nanojunction between two macroscopic electrodes is connected to a battery, electrical current flows across it. The battery provides, and maintains, the charge imbalance between the electrode surfaces needed to sustain steady-state conduction in the junction. This static...

Quantum Mechanics: Periodic Potentials and Kronig-Penney Model
Series | 09 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The Kronig-Penney model is a simple approximation of a solid. The potential consists of a periodic arrangement of delta functions, square well or Coulomb well potentials. By means of epitaxial growth techniques artificial semiconductor superlattices can be realized, which behave very similar to...
