Emphasis is placed on analogies between the various systems rather than on advanced or specialized aspects, with the purpose of illustrating common ideas within different domains of physics. Starting from a basic knowledge of quantum mechanics and classical electromagnetism, the exposition is self-contained and explicitly details all steps of the derivations. The new edition features a substantially new treatment of nucleon pairing.This shows that a diagram does not necessarily correspond to a physically realizable process: it is still necessary that it ... 9.12g is called the vacuum polarization diagram. ...
