|
Physics 4Q03 Lecture 26: This lecture works through how Poincare generators (4-momentum and the angular momentum tensor) transform in quantum relativity. A sketch is given of the argument for the…

|
Physics 4Q03 Lecture 21: This lecture describes how the electromagnetic vector potential (ie photons) couple to nonrelativistic charged particles, constructing the interactions by `gauging' the…
