This study introduces a novel approach for solving the cosmological fieldequations within scalar field theory by employing the Eisenhart lift. The fieldequations are reformulated as a system of geodesic equations for the Eisenhartmetric. In the case of an exponential potential, the Eisenhart metric is shownto be conformally flat. By applying basic geometric principles, a new set ofdynamical variables is identified, allowing for the linearization of the fieldequations and the derivation of classical cosmological solutions. However, thequantization of the Eisenhart system reveals a distinct set of solutions forthe wavefunction, particularly in the presence of symmetry breaking at thequantum level.
