摘要
Recent experimental and molecular dynamics results give evidence for the existence of the discrete solitons (DS's), a.k.a. intrinsic localized modes (ILM's), discrete breathers (DB's) and quodons, which are stable, highly localized lattice excitations that can transfer energy along close-packed crystal directions. The DS interaction with crystal defects results in the amplification of the reaction rates, such as atom ejection and diffusion. In this paper, recent results on the DS detecting in three-dimensional crystal structures by means of molecular dynamics are discussed, and a new method of the rate theory modification in solids under irradiation is presented.
