We study the zero-point energy of a massless scalar field subject to spheroidal boundary conditions. Using the zeta-function method, the zero-point energy is evaluated for small ellipticity. Axially symmetric vector fields are also considered. The results are interpreted within the context of QCD flux tubes and the MIT bag model.

متن کاملConvection in Slab and Spheroidal Geometries
Three-dimensional numerical simulations of compressible turbulent thermally driven convection, in both slab and spheroidal geometries, are reviewed and analyzed in terms of velocity spectra and mixing length theory. The same ideal gas model is used in both geometries, and resulting ows are compared. The Piecewise-Parabolic Method (PPM), with either thermal conductivity or photospheric boundary ...
متن کاملReviewing the Zero Point Energy
A review of recent developments in the study of the Zero Point Energy (ZPE) is made. The origin and behavior of the electromagnetic fields making up the vacuum ZPE is elucidated. From this it is deduced that the ZPE should increase with time even in a static universe such as Narliker and Arp propose. The small oscillations that a static cosmos undergoes will add a variable component to the over...
متن کاملZero Point Energy and Gigantism in Fossils
The Zero Point Energy (ZPE) governs the physical properties of the vacuum, including the electric permittivity and magnetic permeability. Terrestrial and astronomical evidence suggest that the ZPE has increased over the lifetime of the universe. This increase has been shown to result in reduced electric current strengths and voltages, as well as slower electric and magnetic interactions. These ...
