Abstract
AbstractWe have derived the quantum vacuum pressure pvac as a primary entity, removing a trivial and a gauge terms from the cosmological constant‐like part (the zeroth term) of the effective action for a matter field. The quantum vacuum energy density appears a secondary entity, but both are of expected order. Moreover pvac and are dynamical, and therefore they can be used in the Einstein equations. In particular, they could dynamically support the holographic dark energy model as well as the “thermodynamic” one.
