The false vacuum has non-zero vacuum energy and can drive exponential expansion if not coupled with gravity. Upon decay of the false vacuum, the quintessence field is released and begins to evolve. We assumed conditions where the effective scalar potential gradient must satisfy ?Veff&gt;A, characterised by a pressure term approximately ?p/p&gt;O(?) invoking the string swampland criteria. We then derived the effective potential of the scalar with an upper bound on the coupling constant ?&lt;0.6. Further analysis revealed that Veff shows a slow-roll behaviour for 0.1&gt;?&gt;-0.04 in the effective dark energy equation of state (EoS) -0.8 Subject The topic of the resource dark energy; false vacuum; Quintessence; string swampland; ?-cold dark matter Publisher An entity responsible for making the resource available Springer Relation A related resource ISSN: 3044289; CODEN: PRAMC Language A language of the resource English Type The nature or genre of the resource Article Rights Information about rights held in and over the resource All Open Access; Green Open Access Format The file format, physical medium, or dimensions of the resource online
