dc.description.abstractThe low-frequency second-order singularity is found in the permittivity of isotropic and homogeneous model system of charged particles consisting of electrons and boson nuclei. This singularity is caused by the existence of a Bose–Einstein condensate for nuclei. The result obtained for the model under consideration leads to the existence of the “nuclei superconductivity”. Since the system permittivity is obtained for arbitrary strong Coulomb interaction, we suppose that the model can describe also atomic systems with interatomic interaction. In this connection the possible applicability of this model system to weakly interacted Bose systems and to superfluid He II, usually considering as the system of neutral “atoms”, is discussed. In parallel, we discuss the unsolved and principal question about bosonization to clarify which kind of objects should be considered as real bosons, in particular, in He II. In the model under consideration in two-component Coulomb system only nuclei can be considered as bosons, assuming that nuclear forces can provide bosonization of protons and neutrons. The result obtained can be experimentally verified in weakly non-ideal Bose gases and superfluid He II. This is especially actual due to recently discovered electrical activity in superfluid helium.eng
