Web4 mar. 2024 · One class of single-field inflationary models compatible with the recently-conjectured Swampland criteria would be those in which a Hubble slow-roll arameter ϵH is not the same as ϵV ∼ ( V′/V) 2. However, a roadblock for these models (with a convex potential) lie in the unacceptably high tensor-to-scalar ratio, r, generically predicted by them.

WebMultifield component allows to add/reorder/remove multiple instances of a field. In the simplest case this is a simple form input field (e.g. textfield, textarea) but it can also be a complex component acting as an aggregate of multiple subcomponents (e.g. address entry). The field to be included is defined in the subnode named field . WebWe study the preheating phase for multifield models of inflation involving nonminimal couplings.
