Hubble expansion and structure formation in time varying vacuum models [PDF]
Physical Review D, 2009 We investigate the properties of the FLRW flat cosmological models in which the vacuum energy density evolves with time, $ (t)$. Using different versions of the $ (t)$ model, namely quantum field vacuum, power series vacuum and power law vacuum, we find that the main cosmological functions such as the scale factor of the universe, the Hubble ...
