Charge Motion along Polynucleotide Chains in a Constant Electric Field Depends on the Charge Coupling Constant with Chain Displacements
A. N. Korshunova, V. D. Lakhno
Various regimes of a charge motion along a chain in a constant electric field are investigated. This motion is simulated on the basis of the Holstein model. Earlier studies demonst…
Dependence of the nature of the Holstein polaron motion in a polynucleotide chain subjected to a constant electric field on the initial polaron state and the parameters of the chain
A. N. Korshunova, V. D. Lakhno
In this work, we consider the motion of a polaron in a polynucleotide Holstein molecular chain in a constant electric field. It is shown that the character of the polaron motion in…
Pekar's Ansatz and the Strong Coupling Problem in Polaron Theory
V. D. Lakhno
A detailed consideration is given to the translation-invariant theory of Tulub polaron constructed without the use of Pekar ansatz. A fundamental result of the theory is that the v…
A new type of localized fast moving electronic excitations in molecular chains
A. N. Korshunova, V. D. Lakhno
It is shown that in a Holstein molecular chain placed in a strong longitudinal electric field some new types of excitations can arise. This excitations can transfer a charge over l…
Excitation of Bubbles and Breathers in DNA and Their Interaction with the Charge Carriers
V. D. Lakhno, A. P. Chetverikov
The nonlinear excitations induced in DNA by external force are considered on the basis of Peyrard-Bishop-Dauxois model. It is shown that such impact can lead to creation of bubbles…
Theoretical and Experimental Investigations of DNA Open States
A. S. Shigaev, O. A. Ponomarev, V. D. Lakhno
Literature data on the properties of DNA open states are reviewed and analyzed. These states are formed as a result of strong DNA fluctuations and have a great impact on a number o…
