Ground State Energy for Massive Fields and Renormalisation
Abstract
We discuss the renormalisation of the ground state energy of massive fields obeying boundary conditions, i.e., of the Casimir effect, and emphasise the role of the mass for its understanding. This is an extended abstract of a talk given at the topical group meeting on Casimir Forces at the Harvard-Smithsonian Center for Astrophysics on March 15-29, 1998.
