3.2 Model with a single fermion

A graph of V (φ) is depicted in Figure 1. Here, it is obtained by summing the function

Table 1: The tensor-to-scalar ratio r and the e-folding number N for several vaules of f.

3.3 Model with multiple fermions

Next, let us consider a combination of these cos-type potentials. We have now two fermions ψ1 and ψ2. Each fermion has the values of α, β and qψ as shown in Table 2, and then the potential is written as

Table 2: The values of α, β and qψ.
