Abstract
We study the influence of temperature on large polarons in DNA molecules. Employing the mean field approximation we derive the slight generalization of the SSH Hamiltonian with temperature dependent parameters. It was found that the degree of the modification of system parameters is very weak at physiologically relevant temperature which indicates that the free acoustic polarons as charge carriers may be responsible for DNA conductivity.
Highlights
Charge migration in DNA molecule is the subject of great scientific and practical interest
We study the influence of temperature on large polarons in DNA molecules
Its elucidation on microscopic level would be essential for the understanding of the some basic phenomena in biochemistry and for further progress in DNA based molecular technologies and in molecular electronics
Summary
Charge (electron, hole) migration in DNA molecule is the subject of great scientific and practical interest. We study the influence of temperature on large polarons in DNA molecules. Employing the mean field approximation we derive the slight generalization of the SSH Hamiltonian with temperature dependent parameters.
