Overview

This framework demonstrates late-time cosmic acceleration mechanisms, alleviating cosmological tensions through coherence dynamics.

Key Points

  • The aim is to present a coherence-driven cosmological framework that explains cosmic acceleration and addresses cosmological tensions.
  • Introduced a dynamical coherence regulator λ(z) to model cosmic evolution.
  • Modified expansion history based on coherence principles.
  • Used Type Ia supernovae and BAO data for validation.
  • Analyzed structure formation and growth-rate observable fσ8(z).
  • Shifted the inferred value of the Hubble constant from 68.5 to 73 km/s/Mpc, reducing the Hubble tension.
  • Generated mild suppression in growth-rate observable, improving correlations with redshift-space distortion.
  • Provided predictions that differentiate the model from ΛCDM and dark-energy scenarios.
