Local expressions for one-loop calculations

Research output: Contribution to journalArticlepeer-review


We develop local expressions for the contributions of the short-wavelength vacuum modes to the one-loop vacuum energy. These expressions significantly improve the convergence properties of various "brute-force" calculational methods. They also provide a continuous series of approximations that interpolate between the brute-force calculations and the derivative expansion.
