Abstract

Harmonic one dimensional lattice with an additional Morse potential on site has been used to describe DNA macromolecules properties. We analyze a modification of this lattice introducing a symmetric Morse potential. The existence and stability of the breather is studied in this modified system. We obtain harmonic bifurcation and determine the effective mass of the mobile breather.
