# Local zeta regularization and the scalar Casimir effect IV. The case of a rectangular box

May 13, 2015

Applying the general framework for local zeta regularization proposed in Part
I of this series of papers, we compute the renormalized vacuum expectation
value of several observables (in particular, of the stress-energy tensor and of
the total energy) for a massless scalar field confined within a rectangular box
of arbitrary dimension.
