This article will review quantum particle creation in expanding universes. The emphasis will be on the basic physical principles and on selected applications to cosmological models. The needed formalism of quantum field theory in curved spacetime will be summarized, and applied to the example of scalar particle creation in a spatially flat universe. Estimates for the creation rate will be given and applied to inflationary cosmology models. Analog models which illustrate the same physical principles and may be experimentally realizable are also discussed.

  1. The effects of non Bunch-Davies initial conditions on gravitationally produced relics

    gr-qc 2026-03 conditional novelty 6.0 of 10

    Non-Bunch–Davies initial conditions can drastically change gravitationally produced vector dark matter abundances, opening a wider viable mass range.

  2. Towards a unified quantum field theory of dark energy and inflation: unstable de Sitter vacuum and running vacuum

    gr-qc 2026-01 conditional novelty 6.0 of 10

    The vacuum energy of quantum fields, computed exactly in de Sitter spacetime and then allowed to decay into radiation, can drive H^4-powered inflation and leave a slowly running dark energy δρ_vac ~ m_Pl^2 H^2, unifyi...

  3. Gravitons and Temperature Fluctuation Correlations from Inflation

    gr-qc 2025-07 conditional novelty 6.0 of 10

    Inflation-produced gravitons in a squeezed quantum state are predicted to create distinctive anti-correlations, about 20% in angle and 50% in redshift, in CMB temperature fluctuations.

  4. Setting up stasis with gravitational interactions

    hep-ph 2025-06 conditional novelty 6.0 of 10

    PBH evaporation can fill a decaying particle tower with Ω_l ∝ m_l^{+1} or m_l^{-1}, and CGPP with α = 0, 1/2, or 2, matching the conditions needed for cosmological stasis.

  5. Conformal symmetry, SM and Gravity

    hep-th 2026-07 conditional novelty 5.0 of 10

    A Weyl-invariant SM+mirror-dark-matter+gravity model is developed via algebraic renormalization; its conformal cohomology is claimed trivial, and the required counterterms could — the author concedes not conclusively ...

  6. Anomaly footprints in SM+Gravity

    hep-th 2025-10 conditional novelty 4.0 of 10

    A mirror right-handed copy of the standard model, sharing only gravity and SU(2), is claimed to be anomaly-free, proposed as dark matter, and wrapped in a Weyl-invariant early-universe solution.

  7. Field theory vacuum and entropic dark energy models

    gr-qc 2025-07 unverdicted novelty 4.0 of 10

    The paper derives new dark energy models from the postulate that the arbitrary oscillator mass in a free field's Hamiltonian is a real, gravitating mass contributing vacuum energy density μK^3.

  8. Investigating $f(R)$-Inflation: background evolution and constraints

    astro-ph.CO 2025-07 conditional novelty 4.0 of 10

    A Jordan-frame f(R) model with particle creation during inflation is fitted to DESI and Pantheon+ data, yielding H0=71.04 and a claimed reduction of the Hubble tension to about 1.6-2.8 sigma.

  9. Running Vacuum in the expanding Universe: a unified QFT paradigm for Inflation and Dark Energy

    gr-qc 2026-06 unverdicted novelty 3.0 of 10

    The running vacuum model derives dynamical vacuum energy from QFT in curved spacetime, using H^4 terms for inflation and H^2 terms for dark energy while G evolves logarithmically.

  10. Alternative Derivations of Hawking Radiation

    gr-qc 2025-05 unverdicted novelty 2.0 of 10

    A review chapter that reproduces and compares the tunneling, anomaly, and Green's function derivations of Hawking radiation, recovering the Hawking temperature and noting open justifications.
