It is well known that non-minimal couplings with the Holst invariant can generate a quasi-pole inflationary behaviour resulting in a Starobinsky-like phenomenology. The same quasi-pole behaviour can also be used in order to ``flatten'' the scalar potential in the Dark Energy era providing a successful framework for quintessential inflation.…","published":"2026-09-29T04:00:00Z","seen":"2026-09-29T07:46:41Z","lang":"en","source":{"id":"arxiv-astro-ph","name":"arXiv astro-ph (astrophysics)","domain":"arxiv.org","outlet":{"wikidata":"Q118398","name":"arXiv","type":"website","country":"US","designations":["bibliographic database","disciplinary repository","online database","open science tool","preprint server","website"]}},"via":"arxiv-astro-ph","topics":["space","astrophysics","gr-qc","astro-ph.co","hep-ph"],"authors":["Konstantinos Dimopoulos, Christian Dioguardi, Ioannis D.
