The non-relativistic limits of the Maxwell and Dirac equations: the role of Galilean and gauge invariance
The aim of this paper is to illustrate four properties of the non-relativistic limits of relativistic theories: (a) that a massless relativistic field may have a meaningful non-relativistic limt, (b) that a relativistic field may have more than one non-relativistic limit, (c) that coupled relativist...
