Biomathematics Seminar: Influence of electromagnetic field on soliton mediated charge transport in macromolecules
11 March 2014 14:00 in Department of Mathematical Sciences
A short review of the soliton mechanism of charge transport in macromolecules will be given. Such solitons describe bound states of electrons and local distortions of alpha-helical macromolecules, and can be responsible for the charge transport accompanying metabolism of living organisms. Within this mechanism I will demonstrate that external electromagnetic field has a resonant effect on soliton dynamics. At certain frequencies solitons can be dissociated, and at another frequencies their dynamics qualitatively changes. I will also discuss ratchet dynamics of solitons, i.e., drift of solitons, induced by the external electromagnetic field. These results put some light on the resonant non-thermal biological effects of oscillating fields.
