Gravitation of the Casimir Effect and the Cosmological Non-Constant
Whereas the total energy in zero-point fluctuations of the particle physics vacuum gives rise to the cosmological constant problem, differences in the vacuum give rise to real physical phenomena, such as the Casimir effect. Hence we consider the zero-point energy bound between two parallel conducting plates — proxy for a solid slice of cosmological constant — as a convenient laboratory in which...
متن کاملThe Cosmological Redshift as a Virtual Effect of Gravitation
“Will the universe expand forever?” (Gott et al. 1974, 1976) This has been one of the main questions of cosmology since the interpretation of the redshifted light of remote stars and galaxies as a Doppler phenomenon was accepted by the majority of cosmologists. Prodigious efforts have been made to estimate the amount of matter in the universe and to determine quantities such as the Hubble param...
متن کاملInverse square law of gravitation in (2+1)-dimensional space-time as a consequence of Casimir energy
The gravitational effect of vacuum polarization in space exterior to a particle in (2+1)-dimensional Einstein theory is investigated. In the weak field limit this gravitational field corresponds to an inverse square law of gravitational attraction, even though the gravitational mass of the quantum vacuum is negative. The paradox is resolved by considering a particle of finite extension and taki...

متن کاملHe and Casimir Effect
The friction force on the moving interface between two different vacuum states of superfluid 3He is considered at low temperature. Since the dominating mechanism of the friction is the Andreev reflection of the massless " relativistic " fermions, which live on the A-phase side of the interface, the results are similar to that for the perfectly reflecting mirror moving in the quantum vacuum.
