| Popis: | We develop a method to compute the vacuum polarization energy for coupled scalar fields with different masses scattering off a background potential in one space dimension. As an example we consider the vacuum polarization energy of a kink-like soliton built from two real scalar fields with different mass parameters. Comment: 14 pages, 5 figures, matches journal version, references added (surprisingly many) |
