We investigate the dynamics of two lattice models for the denaturation of the DNA double helix associated with different degrees of freedom of the molecule. Using numerical simulations or the transfer integral method for the statistical mechanics, we investigte the formation of the large amplitude nonlinear excitations leading to denaturation. We show that a mechanism involving an energy localization analogous to self focusing may start the denaturation locally.
