This model contains a free parameter, $\\eta$, which quantifies the non-minimal derivative coupling and a parameter $\\alpha$ which characterize the constant-roll condition. In this scenario, using the Hamilton-Jacobi-like formalism, an ansatz for the Hubble parameter (as a function of the scalar field) and some restrictions on the model parameters, we found new exact solutions for the inflaton potential which include power-law, de Sitter, quadratic hi","authors_text":"A.
