Abstract: Tachyon inflation is one of the most attractive models of noncannonical inflation motivated by string theory. In this work we revisit the constraints on tachyon inflation with inverse $\cosh$ potential and exponential potential considering reheating,… read more here.

Abstract: We study the constant-roll tachyon inflation with large and small η. In previous studies, only the constant-roll tachyon inflation with small η is consistent with the observations. We find that the duality between the constant-roll… read more here.
