Physics 4Q03 Lecture 28: This lecture applies the framework of relativistic quantum fields to the simplest case of a spinless particle and constructs the Klein Gordon hamiltonian and some of its…
|
|
Physics 4Q03 Lecture 12: This lecture summarizes the position space formalism of the previous lecture and introduces simple self-interactions.
|
|
Physics 4Q03 Lecture 02. This lecture describes several issues associated with multiple-particle states in quantum mechanics, including the classification of all particles as bosons or fermions and…

|
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…
|
|
Physics 4Q03 Lecture 18: This lecture continues the previous one on photons in electromagnetism, and provides a sermon about UV and IR divergences and why you can use any regularization you like to…
