标题： Models for energy and charge transport and storage in biomolecules

摘要： 考虑了两种关于生物分子中能量和电荷传输与存储的模型。 基于包含DNA碱基对之间长程色散相互作用（LRI's）的离散非线性薛定谔方程的模型被提出，用于描述DNA分子的非线性动力学。 我们证明，LRI's 负责存在一个双稳态区间，在该区间内，每个总能量值下两个稳定的静态状态——一个窄的、钉扎状态和一个宽的、移动状态——共存。 展示了在钉扎状态和移动状态之间进行可控切换的可能性。 该机制可能对控制DNA分子中的能量存储和传输具有重要意义。 另一个模型被提出用于描述蛋白质和其他非谐波生物分子中的非线性激发。 我们证明，在高度非谐波系统中，Davydov 和 Boussinesq 孤子的束缚态可以存在。 显示英文摘要

摘要： Two models for energy and charge transport and storage in biomolecules are considered. A model based on the discrete nonlinear Schrodinger equation with long-range dispersive interactions (LRI's) between base pairs of DNA is offered for the description of nonlinear dynamics of the DNA molecule. We show that LRI's are responsible for the existence of an interval of bistability where two stable stationary states, a narrow, pinned state and a broad, mobile state, coexist at each value of the total energy. The possibility of controlled switching between pinned and mobile states is demonstrated. The mechanism could be important for controlling energy storage and transport in DNA molecules. Another model is offered for the description of nonlinear excitations in proteins and other anharmonic biomolecules. We show that in the highly anharmonic systems a bound state of Davydov and Boussinesq solitons can exist.
