Dynamics driven by the Trace Anomaly in FLRW Universes
Dynamics driven by the Trace Anomaly in FLRW Universes
By means of a semiclassical analysis we show that the trace anomaly does not affect the cosmological constant. We calculate the evolution of the Hubble parameter in quasi de Sitter spacetime, where the Hubble parameter varies slowly in time, and in FLRW spacetimes. We show dynamically that a Universe consisting …
