We demonstrate that the combination of the ideas of unimodular gravity, scale invariance, and the existence of an exactly massless dilaton leads to the evolution of the universe supported by present observations: inflation in the past, followed by the radiation and matter dominated stages and accelerated expansion at present. All mass scales in this type of theories come from one and the same source.

    gr-qc 2026-06 unverdicted novelty 5.0

    Exact vacuum FLRW solutions in q-deformed Brans-Dicke cosmology yield constant EoS and deceleration parameters that can mimic standard cosmological fluids for restricted parameter ranges.

  2. QCD axion from broken scale symmetry

    hep-th 2026-05 unverdicted novelty 4.0

    Dilaton from broken scale symmetry meets all conditions for non-compact QCD axion cosmology including non-periodicity and timely domain-wall collapse.
