Kurzbeschreibung (Abstract)
As a step towards deriving universal amplitude ratios of the superconductive phase transition we calculate the vacuum energy density in the symmetric phase of O(N)-symmetric scalar QED in D=4-e dimensions in an e expansion using the minimal subtraction scheme commonly denoted by MS. From the diverging parts of the diagrams, we obtain the renormalization constant of the vacuum Zv which also contains information on the critical exponent a of the specific heat. As a side result, we use an earlier two-loop calculation of the effective potential [H. Kleinert and B. Van den Bossche, cond-mat/0104102] to determine the renormalization constant of the scalar field Zf up to two loops.
