On the effect of force on DNA in the Peyrard-Bishop-Dauxois model
I. V. Likhachev, V. D. Lakhno
This paper presents a numerical study of the dynamics of DNA double helix breakage under the influence of external forces using the Peyrard-Bishop-Dauxois (PBD) model. The PBD mode…

On the comparison of models and experiments in the study of DNA open states: the problem of degrees of freedom
Alexey S. Shigaev, Victor D. Lakhno
Simple mechanical models of DNA play an important role in studying the dynamics of its open states. The main requirement when developing a DNA model is the correct selection of its…

On the thermodynamics of DNA in the Peyrard-Bishop-Dauxois model
Ilya V. Likhachev, Alexey S. Shigaev, Victor D. Lakhno
Based on the direct method of molecular dynamics, the temperature dependence of energy, partition function, entropy and free energy, describing the first-order phase transition, is…
