Casimir Energy for a Purely Dielectric Cylinder by the Mode Summation Method

arXiv:hep-th/0504207 · doi:10.1016/j.physletb.2005.06.073

Abstract

We use the mode summation method together with zeta-function regularization to compute the Casimir energy of a dilute dielectric cylinder. The method is very transparent, and sheds light on the reason the resulting energy vanishes.
