Electromagnetic Casimir-Polder Interaction for a Conducting Cone
arXiv:2308.11869 · doi:10.3390/physics5040065
Abstract
Using the formulation of the electromagnetic Green's function of a perfectly conducting cone in terms of analytically continued angular momentum, we compute the Casimir-Polder interaction energy of the cone with a polarizable particle. We introduce this formalism by first reviewing the analogous approach for a perfectly conducting wedge, and then demonstrate the calculation through numerical evaluation of the resulting integrals.
