Physics 4Q03 Lecture 03: This lecture provides the foundation of much of what follows: the definition and properties of creation and annihilation operators. These operators provide a basis in terms…
|
|
Physics 4Q03 Lecture 04: This lecture extends the notions of creation and annihilation operators to fermions, and derives the anticommutation algebra that these satisfy. The lecture also sketches out…

Physics 4Q03 Lecture 07: This lecture applies Fermi's Golden Rule to evaluate the rate for photon emission by an excited atom. This example is also used to illustrate the phenomenon of…
|
|
4Q03 Lecture 08: This lecture continues to convert Fermi's Golden Rule to continuum normalization, doing so for a simple absorption process and then for a general scattering process, defining…
