We investigate the statistical mechanics of a simple lattice model for the denaturation of the DNA double helix. The model consists of two chains connected by Morse potentials representing the H bonds. We determine the temperature dependence of the interstrand separation and we show that a mechanism involving an energy localization analogous to self-focusing may initiate the denaturation.
