    Particle number projection on a spatial domain

    L.M. Robledo

    The formalism of particle number on a spatial domain for mean field wave functions with pairing is revisited to account for the case where finite dimensional basis are used. The formulas differ from the ones previously used in the literature. It is shown that the present formalism has the right limit in the well known case of zero pairing whereas the other formalism do not satisfy this basic requirement. By using a simple one-dimensional model we illustrate the differences in the results for particle number distribution probability obtained with the two methods.

    Super-enhanced Nuclear Fusion in Metal-like Systems and in Condensed Plasmas of Supernova Progenitors

    Hidetsugu Ikegami

    In the scheme of chemonuclear reaction, bulk of itinerant s-electrons revealing the thermodynamical liquid activity in metallic systems undergo contact interaction with atomic nuclei and therein nucleons, inducing contagiously thermodynamical liquid activity among the bulk of nuclei under the irreversible action of Nature towards the chemical potential minimum resulting in the united spontaneous, irreversible atomic and nuclear reactions. The chemonuclear reaction, moreover, is enhanced with astronomical figures besides the enhancement of few particle processes (e.g., in the electron-screened pycnonuclear fusion). In the systems of metal-like hydride/deuteride and electron donor mixtures, self-sustained H-H and D-D chemonuclear fusion may take place. In these systems, however, some unforeseen phenomena are induced, e.g., radiation-less fusion and -ray missing positron annihilation.
