Taken together, our theoretical framework successfully anticipates various facets of the CDW transition, encompassing the transition temperature, the absence of M mode condensation, and the observed lack of softening. This significant agreement with experimental data carries two noteworthy implications:
(1) The study of the CDW mechanism can be decoupled from phenomena arising in the CDW phase.
(2) Quantum effects of the lattice may also exert a crucial influence on the emergent physics in the CDW state, akin to their role in the CDW mechanism.
