Shell Effects in Bubble Nuclei, Atomic Clusters, and Inhomogeneous Neutron Matter

Abstract

We analyze the character of the shell effects/Casimir energy in inhomogeneous fermion systems. We estimate magnitude of the shell effects and discuss their dependence on a number of physical parameters (geometry, fermion density, temperature).
