Abstract

The charge transport processes in biological macromolecules are studied within the nonlinear electrosoliton mechanism. The interaction between few electrosolitons in a one-dimensional electron-phonon system is investigated. It is shown that in a singlet state the minimum of energy corresponds to a bisoliton. In a triplet state the autolocalized state is described by two electrosolitons which are separated from one another by some finite distance determined by the nonadiabatic terms of the Hamiltonian.

摘要

在非线性电孤子机制下研究了生物大分子中的电荷传输过程。研究了一维电子 - 声子系统中少数电孤子之间的相互作用。结果表明,在单重态下,能量最小值对应于双孤子。在三重态下,自局域态由两个电孤子描述,它们彼此相隔一定的有限距离,该距离由哈密顿量的非绝热项确定。
