    "abstract": "The positioning of one or more bubbles inside a many fermion or boson system,\ndoes not affect the volume, surface or curvature terms in the liquid drop\nexpansion of the total energy. If Coulomb effects are irrelevant, the only\ncontribution to the ground state energy of a system with one or more voids\narises from quantum effects, which is similar to the Casimir effect in vacuum\nor in critical phenomena. We discuss the characteristics of such systems, the\ninterplay among various effects, such as shell corrections and chaotic\nbehavior, and briefly mention the role of the temperature and pairing.",
