A previous study presented an approach where the collective modes arise from the standard procedure of diagonalizing a Hamiltonian that has a potential with nondiagonal quadratic terms. The present work further elucidates the physical picture implied by this formalism. For demonstration purposes, the application of this formalism to a standard test system, liquid argon, is highlighted.
