Title: On the equivalence between the effective potential and zero-point energy
Author: Nogueira, JA
Maia, A
Abstract: We investigate a possible difference between the effective potential and the zero-point energy. We define the zero-point ambiguity (ZPA) as the difference between these two definitions of vacuum energy. Using the zeta function technique, in order to obtain renormalized quantities, we show that ZPA vanishes, implying that both of the above definitions of vacuum energy coincide for a large class of geometries and a very general potential. In addition, we show explicitly that an extra term, obtained by E. Myers some years ago for the ZPA, disappears when a scale parameter mu is consistently introduced in all zeta functions in order to keep them dimensionless.
