离散脉冲器的若干方面与新方向
摘要
我们描述了关于离散脉冲器（DBs）在具有光学线性声子和声学线性声子两类动力系统中的存在性证明所涉及的结果。标准方法是通过从反连续极限延续 DBs 实现的。 presented a new approach, which is purely variational. We also review some numerical results on intraband DBs in random nonlinear systems. Some non-conventional physical applications of DBs are suggested. One of them is understanding slow relaxation properties of glassy materials. Another one concerns energy focusing and transport in biomolecules by targeted energy transfer of DBs. A similar theory could be used for describing targeted charge transfer of nonlinear electrons (polarons) and, more generally, for targeted transfer of several excitations (e.g. Davydov soliton).
