Peierls-Nabarro potential barrier for highly localized nonlinear modes.
We consider two types of strongly localized modes in discrete nonlinear lattices. Taking the lattice nonlinear Schrodinger (NLS) equation as a particular but rather fundamental example, we show that (1) the discreteness effects may be understood in the "standard" discrete NLS model as arising from an effective periodic potential similar to the Peierls-Nabarro (PN) barrier potential for kinks in...
متن کاملLocalized modes in a chain with nonlinear on-site potential
Localized modes are analysed for a chain with nonlinear on-site potential using an approximation based on the discrete nonlinear Schr0dinger equation. It is pointed out that such localized modes exist in the parameter domains where the system displays modulational instability. Otherwise, nonlinear modes may appear in the form of dark-profile localized structures, and two types of such structure...
متن کاملIntrinsic Localized Modes in Proteins
Protein dynamics is essential for proteins to function. Here we predicted the existence of rare, large nonlinear excitations, termed intrinsic localized modes (ILMs), of the main chain of proteins based on all-atom molecular dynamics simulations of two fast-folder proteins and of a rigid α/β protein at 300 K and at 380 K in solution. These nonlinear excitations arise from the anharmonicity of t...
متن کاملLocalized Modes in Mechanical Cantilever Array”
In 1988, intrinsic localized mode (ILM) was theoretically discovered as a temporary periodic and spatially localized solution in a nonlinear coupled oscillator. This discovery triggered wide-spread investigations on energy localization phenomena in spatially discrete systems. In particular, observations of the ILM in micro-mechanical cantilever arrays enable us to expect that energy localizatio...
متن کاملLocalized vibration modes in free anisotropic wedges.
Propagation of flexural localized vibration modes along edges of anisotropic wedges is considered in the framework of the geometrical-acoustics approach. Its application allows for straightforward evaluation of the wedge-mode velocities in the general case of arbitrary elastic anisotropy. The velocities depend on the wedge apex angle and on the mode number in the same way as in the isotropic ca...
