| contents | The influence of an external oscillating in time magnetic field on the dynamics of the Davydov's soliton is investigated. It is shown that it essentially depends not only on the amplitude and frequency of the magnetic field, but also on the field orientation with respect to the molecular chain axis. The soliton velocity and phase are calculated. They are oscillating in time functions with the frequency of the main harmonic, given by the external field frequency, and higher multiple harmonics. It is concluded that such complex effects of external time-depending magnetic fields on the dynamics of solitons modify the charge transport in low-dimensional molecular systems, which can affect functioning of the devices based on such systems. These results suggest also the physical mechanism of therapeutic effects of oscillating magnetic fields, based on the field influence on the dynamics of solitons which provide charge transport through biological macro-molecules in the redox processes. |
