Quantum vacuum and accelerated expansion
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–Lemaitre–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.
