FIELD THEORETICAL APPROACHES TO THE SUPERCONDUCTING PHASE TRANSITION

Flavio Nogueira

Freie Universität Berlin

Several field theoretical approaches to the superconducting phase transition are discussed. Emphasis is given to theories of scaling and renormalization group in the context of the Ginzburg-Landau theory and its variants. Also discussed is the duality approach, which allows the access to the strong coupling limit of the Ginzburg-Landau theory.
