Researchers from Institute of Mathematics Report Findings in Low Dimensional Structures (A new type of localized fast moving electronic excitations in molecular chains)

By a News Reporter-Staff News Editor at Physics Week -- Fresh data on Low Dimensional Structures are presented in a new report. According to news originating from Moscow Region, Russia, by VerticalNews correspondents, research stated, "It is shown that in a Holstein molecular chain placed in a strong longitudinal electric field some new types of excitations can arise. These excitations can transfer a charge over large distance (more than 1000 nucleotide pairs) along the chain retaining approximately their shapes."

Our news journalists obtained a quote from the research from the Institute of Mathematics, "Excitations are formed only when a strong electric field either exists or quickly arises under especially preassigned conditions. These excitations transfer a charge even in the case when Holstein polarons are practically immobile. The results obtained are applied to synthetic homogeneous PolyG/PolyC DNA duplexes."

According to the news editors, the research concluded: "They can also be provide the basis for explanation of famous H.W. Fink and C. Schonenberger experiment on long-range charge transfer in DNA."
