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 22: This lecture recaps the previous ones and completes the interactions of a nonrelativistic charged particle to include the Coulomb interaction.


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…


Physics 4Q03 Lecture 20: This lecture describes how to construct interactions between electromagnetic fields and the Schrodinger fields that describe slowly moving particles. The interactions…


Physics 4Q03 Lecture 14: This lecture continues the discussion of Bose Einstein condensation and shows how a semiclassical analysis can allow a calculation of the optimal density of condensed…


Physics 4Q03 Lecture 12: This lecture summarizes the position space formalism of the previous lecture and introduces simple selfinteractions.


4Q03 Lecture 10: This lecture computes the energy shift of a particle due to its interaction with another, introducing ultraviolet divergences and the concept of renormalization along the way. The…
