Quintessential inflation in a thawing realization
We study quintessential inflation with an inverse hyperbolic type potential V(ϕ)=V0/cosh(ϕn/λn), where V0, λ and “n” are parameters of the theory. We obtain a bound on λ for different values of the parameter n. The spectral index and the tensor-to-scalar-ratio fall in the 1σ bound given by the Plan...
