Query: Local zeta regularization and the scalar Casimir effect III. The case
  with a background harmonic potential   Applying the general framework for local zeta regularization proposed in Part
I of this series of papers, we renormalize the vacuum expectation value of the
stress-energy tensor (and of the total energy) for a scalar field in presence
of an external harmonic potential.
