Back-Reaction of Super-Hubble Fluctuations, Late Time Tracking and Recent Observational Results
Marco Antonio Cardoso Alvarez, Leila Graef, Robert Brandenberger
Previous studies suggested that the back-reaction of super-Hubble cosmological fluctuations could lead to a dynamical relaxation of the cosmological constant. Moreover, this mechan…
