摘要：

We have derived the quantum vacuum pressure p(vac) 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 (rho) over bar (vac) appears a secondary entity, but both are of expected order. Moreover P-vac and (rho) over bar vac 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. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
