摘要：
Recently there has been much interest in gauge theories applied to condensed matter physics. I show that for a system of non-relativistic electrons coupled to a U(1) gauge field in the presence of a Fermi surface, the beta-function to one-loop order is, for a particular family of gauge choices, independent of the gauge choice.
