abstract

We demonstrate a spontaneous tendency of quantum wave packets to become quasi-classical, providing a classical limit for the Universe dynamics. However, this limit is not maintained in the future (after a critical value of the relational time) and a spreading process is turned on. We show that the onset of an inflationary scenario is not able to make this localization stable of the wave packets for the Bianchi I model. Instead, when we implement a perturbative inflationary scenario for the isotropic Universe a mechanism of stable classicalization of the Universe emerges. This result outlines a sharp difference between the standard relativistic cosmology and a modified $f(R)$ paradigm.

  1. Minimal Proper Time and Deterministic Microstates: Emergent Quantum Fields and Relativistic Spacetime

    hep-th 2026-07 conditional novelty 6.0 of 10

    Coarse-graining deterministic event chains yields Nambu-like QFT with running ħ and IR unitarity, plus an emergent metric selected by Lovelock to Einstein gravity.

  2. Direct detection of solar chameleons with electron recoil data from XENONnT

    hep-ph 2025-11 conditional novelty 5.0 of 10

    XENONnT electron-recoil data bound solar chameleons to log10 β_eff < −6.9, independent of the potential index n for inverse power-law chameleons at the dark-energy scale.
