Quantum Mechanics: Stationary Perturbation Theory
10 Jul 2008  Series  Contributor(s): Dragica Vasileska, Gerhard Klimeck
Stationary perturbation theory is concerned with finding the changes in the discrete energy levels and the changes in the corresponding energy eigenfunctions of a system, when the Hamiltonian of a...

Quantum Mechanics: TimeDependent Perturbation Theory
10 Jul 2008  Series  Contributor(s): Dragica Vasileska, Gerhard Klimeck
Timedependent perturbation theory, developed by Paul Dirac, studies the effect of a timedependent perturbation V(t) applied to a timeindependent Hamiltonian H0. Since the perturbed Hamiltonian...

Quantum Mechanics: WKB Approximation
09 Jul 2008  Series  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: Tunneling
08 Jul 2008  Series  Contributor(s): Dragica Vasileska, Gerhard Klimeck
In quantum mechanics, quantum tunnelling is a micro nanoscopic phenomenon in which a particle violates the principles of classical mechanics by penetrating a potential barrier or impedance higher...

Quantum Mechanics: Time Independent Schrodinger Wave Equation
07 Jul 2008  Series  Contributor(s): Dragica Vasileska, Gerhard Klimeck
In physics, especially quantum mechanics, the Schrödinger equation is an equation that describes how the quantum state of a physical system changes in time. It is as central to quantum mechanics...

Quantum Mechanics: Introductory Concepts
07 Jul 2008  Series  Contributor(s): Dragica Vasileska, Gerhard Klimeck, David K. Ferry
In this section of the Quantum Mechanics class we discuss the particlewave duality and the need for the quantization of energy to explain the blackbody radiation and the photoelectric effect. We...

Quantum Mechanics: Wavepackets
07 Jul 2008  Series  Contributor(s): Dragica Vasileska, Gerhard Klimeck
In physics, a wave packet is an envelope or packet containing an arbitrary number of wave forms. In quantum mechanics the wave packet is ascribed a special significance: it is interpreted to be a...
