Faraji, Elham — Properties of electronic currents along DNA fragments through light pumping

We are working on a model partly borrowed from the standard Davydov-Fröhlich models originally introduced to account for electron-phonon interaction in macromolecules. Under the action of an external electromagnetic field on a DNA protein, the energy transferred to the electron shows an electronic current which can display either a spreading frequency spectrum or a sharply narrow
frequency spectrum. This phenomenology displays a potentially rich variety of electrodynamic interactions of DNA molecules by the electron excitation. This could imply the activation of interactions between DNA and external electromagnetic fields.
