Local zeta regularization and the scalar Casimir effect III. The case with a background harmonic potential

Davide Fermi, Livio Pizzocchero
2015 International Journal of Modern Physics A  
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.
