Vacuum energy fluctuations, the induced cosmological constant and cosmological reconstruction in non-minimal modified gravity models
The one-loop effective action for non-minimal scalar modified gravity on de Sitter background with a constant scalar field is found. The corresponding induced cosmological constant is evaluated. It is shown that quantum effects in non-minimal modified gravity may induce an early-time de Sitter universe even in the situation when such solution does not occur on the classical level. Classical rec...
متن کاملCosmological constant and vacuum energy
The general thermodynamic analysis of the quantum vacuum, which is based on our knowledge of the vacua in condensed-matter systems, is consistent with the Einstein earlier view on the cosmological constant. In the equilibrium Universes the value of the cosmological constant is regulated by matter. In the empty Universe, the vacuum energy is exactly zero, λ = 0. The huge contribution of the zero...
متن کاملVacuum Energy and the Cosmological Constant
We discuss a numerical relation between the cosmological constant Λ [1] and the vacuum energy arising from the Casimir effect [2]. Many recent theories of the elementary particles invoke the existence of extra dimensions, beyond the familiar 4-dimensional space-time manifold. Often these extra dimensions are compact and have a finite range. In a particular model [3] the range R is of the order ...
متن کاملCosmological Acceleration: Dark Energy or Modified Gravity?
The recently observed accelerating cosmological expansion or ”dark energy” may be either a negative pressure constituent in General Relativity (Dark Energy) or modified gravity (Dark Gravity) without any constituent Dark Energy. Lowor high-curvature modifications of Einstein gravity are distinguished by the spacetime (Ricci) curvature of their vacua. If constituent Dark Energy does not exist, s...
متن کاملVacuum Energy Density and Cosmological Constant in dS Brane World
We discuss the vacuum energy density and the cosmological constant of dS5 brane world with a dilaton field. It is shown that a stable AdS4 brane can be constructed and gravity localization can be realized. An explicit relation between the dS bulk cosmological constant and the brane cosmological constant is obtained. The discrete mass spectrum of the massive scalar field in the AdS4 brane is use...
