The matter content of the model is given by a radiation fluid, a Generalized Chaplygin gas, and an ad hoc potential. After writing the Hamiltonian of the model, we notice that the effective potential ($V_{eff}$) depends on four parameters: $A$, $B$ and $\\alpha$ associated with the Generalized Chaplygin gas, and $\\sigma$ associated with the ad hoc potential. Depending on the values of these parameters $V_{eff}$ becomes a double barrier potential.
