Dynamics of impurity attraction and repulsion of an intrinsic localized mode in a driven 1-D cantilever array

Both low frequency and high frequency impurity modes have been produced in a SiN micromechanical cantilever array by illumination with either an infrared or visible laser. When such laser-induced impurities are placed near a driven intrinsic localized mode (ILM) it is either repelled or attracted. By measuring the linear response spectrum for these two cases it was found that vibrational hopping of the ILM takes place when the natural frequency of the ILM and an even symmetry linear local mode are symmetrically located about the driven ILM frequency so that parametric excitation of these two l…

Driven localized excitations in the acoustic spectrum of small nonlinear macroscopic and microscopic lattices

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。

Discrete intrinsic localized modes in a microelectromechanical resonator

Intrinsic Localized Modes (ILMs) or Discrete Breathers (DBs) are produced through a non-linear vibration localization phenomenon. While Anderson localization is due to lattice defects, the nonlinearity of lattices provides the basis for ILM excitation. Over the past two decades, these ILMs have been realized in a wide range of physical systems including photonic crystals, nonlinear atomic lattices, anti-ferromagnets, coupled Josephson junction arrays and coupled cantilevers. This paper brings out the feasibility of exciting ILMs in a standalone mechanical resonator. Through piezoelectric drivi…
