Divergences in the Casimir energy
J.S.Dowker
TL;DR
This paper investigates the divergences in Casimir energy calculations, attributing them to edge effects, and provides insights into how geometric features influence quantum vacuum energies.
Contribution
It identifies edges as the source of divergences in Casimir energy on a semi-circular cylinder, clarifying the role of geometric boundaries.
Findings
Divergences are linked to edges in the geometry.
Edges cause additional contributions to Casimir energy.
Understanding edge effects helps refine Casimir energy computations.
Abstract
The divergence found by Nesterenko, Lambiase and Scarpetta in the Casimir energy on a semi-circular cylinder is attributed to the existence of edges.
