Two-Field Inflationary Model and Swampland de Sitter Conjecture

Abstract

In this paper, we are going to investigate a new perspective of the two-field inflation model with respect to the swampland dS conjecture. At the first step, we study the two-fields inflation model, and apply the swampland conjecture to our model. Then, we calculate some cosmological parameters such as scalar spectrum index, tensor-to-scalar ratio, and compare our results with the recent observational data. Also, we give numerical analysis to show agreement with observational data.

Multi-field cold and warm inflation and the de Sitter swampland conjectures

“…In the context of the swampland conjectures, two-field inflationary models were discussed in refs. [30,31], where in ref. [30] non-canonical kinetic energy terms have been considered.…”
