Is de Sitter space always excluded in semiclassical f (R) gravity?

Casadio, R.; Giugno, A.; Giusti, A. und Faraoni, V (2019): Is de Sitter space always excluded in semiclassical f (R) gravity? In: Journal of Cosmology and Astroparticle Physics, Nr. 6, 005

Abstract

It is shown that the recent corpuscular description of gravity generically excludes de Sitter spacetime in any semiclassical version of f (R) gravity. A phantom phenomenology of the cosmic dynamics is also naturally excluded.
