摘要：

We describe the dynamics of breather modes in DNA in terms of a recent lattice model with an additional interaction in order to take into account the helicoidal structure of the molecule. It is shown that, despite its simplicity, this model exhibits breatherlike modes which can match experimentally observed bubbles propagating along the helix. Numerical simulations of their propagation show these excitations to be long-lived and suggest that they are physically relevant for DNA.
