Static and steady state of polarons in DNA system

الملخص EN

This study investigate in details the effect of the phonon vibration on the electrical properties for some short sequences of DNA.

The theoretical study is based on the Anderson-Holstein model Hamiltonian for small polaron and on the extended Holstein model Hamiltonian for large polaron.

These models provides a convenient description of the charge transport with local and non-local electron –phonon on site interaction.

It is extensively, investigated the properties of the stationary state polaron and the stady state polaron.

Where, It is showed that the system parameters such us local and non-local electron-phonon interactions, the electron interaction between DNA bases, the DNA base vibration frequency and base on site energy all have pronounced effects on all kinds of polarons states .
