小非线性宏观和微观晶格声学谱中的受驱动局域激发
Driven localized excitations in the acoustic spectrum of small nonlinear macroscopic and microscopic lattices
摘要：
明亮和黑暗的旅行，锁定，固有局域模式（ILM）已产生与空间均匀的驱动器在非线性微机械悬臂梁阵列的声谱中的频率。互补的数值模拟表明，一个最小的模式密度，因此阵列的大小，需要形成这样的锁定平稳运行的激发。一个小的1-D反铁磁自旋系统的额外的模拟被用来说明这种均匀驱动运行的ILM应该是一个纳米级原子晶格的通用功能。
英文摘要：
Both bright and dark traveling, locked, intrinsic localized modes (ILMs) have been generated with a spatially uniform driver at a frequency in the acoustic spectrum of a nonlinear micromechanical cantilever array. Complementary numerical simulations show that a minimum density of modes, hence array size, is required for the formation of such locked smoothly running excitations. Additional simulations on a small 1-D antiferromagnetic spin system are used to illustrate that such uniformly driven running ILMs should be a generic feature of a nanoscale atomic lattice.
