Within a genuinely gauge invariant approach recently developed for the computation of the cosmological backreaction, we study, in a cosmological inflationary context and with respect to various observers, the impact of scalar fluctuations on the space-time dynamics in the long wavelength limit. We stress that such a quantum backreaction effect is evaluated in a truly gauge independent way using a set of effective equations which describe the dynamics of the averaged geometry. In particular we show under what conditions the free falling (geodetic) observers do not experience any scalar-induced backreaction in the effective Hubble rate and fluid equation of state.

  1. Tensor-Induced Backreaction in Ultra-Slow-Roll Inflation

    astro-ph.CO 2026-08 conditional novelty 6.0 of 10

    Tensor-induced backreaction in ultra-slow-roll inflation limits the drop of the first slow-roll parameter and suppresses the curvature power spectrum peak from roughly 10^-3 to about 4x10^-6, strongly reducing primord...
