From a macroscopic theory of the quantum vacuum in terms of conserved relativistic charges (generically denoted by q^{(a)} with label a), we have obtained, in the low-energy limit, a particular type of f(R) model relevant to cosmology. The macroscopic quantum-vacuum theory allows us to distinguish between different phenomenological f(R) models on physical grounds.

  1. Thermodynamics of homogeneous Universes: de Sitter, Bonnor-Melvin and static Einstein

    gr-qc 2026-05 unverdicted novelty 5.0

    Three homogeneous universes with distinct matter content obey the same thermodynamic equation for energy density, implying vanishing cosmological constant in vacuum.

  2. Thermodynamics of homogeneous Universes: de Sitter, Bonnor-Melvin and static Einstein

    gr-qc 2026-05 unverdicted novelty 4.0

    De Sitter, Bonnor-Melvin-Λ and static Einstein universes share the same thermodynamic energy-density equation despite dissimilar matter fields, yielding zero cosmological constant in Minkowski vacuum.
