Publication Top Notes

1. Is cosmological data suggesting a nonminimal coupling between matter and gravity?
  • Journal: Physics of the Dark Universe

  • Publication Date: May 2025

  • DOI: 10.1016/j.dark.2025.101861

  • Authors: Miguel Barroso Varela, Orfeu Bertolami

  • Summary: This paper investigates whether current cosmological data supports theories where matter and gravity interact via a nonminimal coupling. The authors compare observational data (e.g., from Pantheon+, DES, DESI, and eBOSS) with predictions from these alternative models and find stronger statistical evidence for nonminimal coupling over standard ΛCDM in several dataset combinations.

2. Gravitational wave polarizations in nonminimally coupled gravity
  • Journal: Physical Review D

  • Publication Date: January 6, 2025

  • DOI: 10.1103/PhysRevD.111.024014

  • Authors: Miguel Barroso Varela, Orfeu Bertolami

  • Summary: This paper explores how nonminimal matter-curvature coupling affects gravitational wave (GW) polarization modes. The analysis suggests that these modified gravity models introduce extra polarization modes, potentially observable by future GW detectors.

3. Chaotic behaviour of the Earth System in the Anthropocene
  • Journal: Evolving Earth

  • Publication Date: January 2025

  • DOI: 10.1016/j.eve.2025.100060

  • Summary: The paper discusses the Earth System’s dynamic instability in the Anthropocene epoch, emphasizing feedback loops and thresholds that could lead to chaotic planetary behavior under continued anthropogenic stress.

4. From a dynamic integrated climate economy (DICE) to a resilience integrated model of climate and economy (RIMCE)
  • Journal: The Anthropocene Review

  • Publication Date: December 2024

  • DOI: 10.1177/20530196231205486

  • Summary: Proposes a shift from Nordhaus’s DICE model to a more resilient framework (RIMCE) that incorporates climate tipping points and adaptive capacity, aiming for a more realistic integration of socio-economic and environmental risks.

5. Gravitational waves from a curvature-induced phase transition of a Higgs-portal dark matter sector
  • Journal: Journal of Cosmology and Astroparticle Physics (JCAP)

  • Publication Date: October 1, 2024

  • DOI: 10.1088/1475-7516/2024/10/104

  • Summary: Analyzes how a phase transition in a Higgs-portal dark matter model, induced by spacetime curvature, could produce detectable gravitational wave signatures. The results connect early-universe particle physics with gravitational wave astronomy.
