- Descrição
- We calculate the vacuum energy density of the electromagnetic and conformally coupled scalar fields confined in the interior of a rectangular waveguide and of a rectangular cavity. We identify the physical measurable vacuum energy density by excluding local functions that once integrated do not depend on any global length parameters. Although this quantity is uniform for both fields between parallel plates we show that in the interior of the waveguide it is non-uniform for the conformally coupled scalar field and uniform for the electromagnetic field. In the interior of the rectangular cavity, it is non-uniform for the electromagnetic field. In the situations where the vacuum energy density is non-uniform, we provide a numerical analysis of the results, showing how their form depend on the boundary conditions and on the global length parameters.
