Abstract

In this paper we consider the possibility of the stable migration of the single vibron excitation in the system consisting of biomolecule and the attached molecular structure. The model is based on the assumption of the vibron self-trapping and the formation of the non-adiabatic polaron quasiparticle. We have shown that, contrary to the prediction of the non-polaronic model, excitation occurs at a large intramolecular distance from its origin with high probability for a time long enough to affect the biochemical processes in which the molecular chain participates.

具有分子结构的分子链中的单激发迁移:小极化子模型
本文考虑了单振子在由生物分子及其附着分子结构组成的体系中稳定迁移的可能性。该模型基于振动子自俘获和非绝热极化子准粒子形成的假设。我们已经证明,与非极化模型的预测相反,激发发生在距离其起源较大的分子内距离处,并且高概率持续足够长的时间,从而影响分子链参与的生化过程。

期刊介绍: The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
