Superconductivity and the Higgs Field

In this video, we explore the Higgs field, which has a nonzero expectation value throughout our universe, even in "empty" space. The Higgs field is very much like a superconducting condensate, and so we will use superconductivity as a way of exploring the Higgs field. The video begins with a crash course on superconductivity, then segues into an in-depth exploration of the Anderson-Higgs mechanism (in which gauge bosons acquire mass, by the consumption of Nambu-Goldstone modes), and finally we'll then explore the Higgs field in the context of the electroweak model.

While the video should stand on its own, so that it's not necessary to buy these books in order to follow along, the books offer a wealth of context and additional insight, so they're worth checking out.
