Abstract

A new approach to extraction of quantum vacuum energy, in the context of the accelerated expansion, is proposed, and it is shown that experimentally realistic orders of values can be derived. The idea has been implemented in the framework of the Friedmann–Lemaître–Robertson–Walker geometry in the language of the effective action in the relativistic formalism of Schwinger's proper time and Seeley–DeWitt's heat kernel expansion.
