Precise and Simple Behavior of Macroscopic Systems: The Case of Superconductivity

We emphasize the theoretical simplicity and experimental precision of superconductivity. Spontaneously broken gauge symmetry and macroscopic occupation of quantum levels lie at the basis of these features. The coherent states formalism proves to be well-suited in clarifying this essential link.
