Breathers in oscillator chains with Hertzian interactions
We prove nonexistence of breathers (spatially localized and time-periodic oscillations) for a class of Fermi-Pasta-Ulam lattices representing an uncompressed chain of beads interacting via Hertz’s contact forces. We then consider the setting in which an additional on-site potential is present, motivated by the Newton’s cradle under the effect of gravity. Using both direct numerical computations...
متن کاملBreathers and surface modes in oscillator chains with Hertzian interactions
We study localized waves in chains of oscillators coupled by Hertzian interactions and trapped in local potentials. This problem is originally motivated by Newton’s cradle, a mechanical system consisting of a chain of touching beads subject to gravity and attached to inelastic strings. We consider an unusual setting with local oscillations and collisions acting on similar time scales, a situati...
متن کاملBreathers in hydrogen-bonded chains
In the framework of the one-component model for hydrogen-bonded chains developed by Zolotaryuk and Pnevmatikos [Phys. Lett. A 143 (1990) 233], we study analytically and numerically breather excitations in the continuum and the discrete-carrier limits. We demonstrate that the breathers show high-stability properties especially in the case when the on-site potential is symmetric. We also consider...
متن کاملDynamical properties of discrete breathers in curved chains with first and second neighbor interactions.
We present the study of discrete breather dynamics in curved polymerlike chains consisting of masses connected via nonlinear springs. The polymer chains are one dimensional but not rectilinear and their motion takes place on a plane. After constructing breathers following numerically accurate procedures, we launch them in the chains and investigate properties of their propagation dynamics. We f...
متن کاملDiscrete Breathers in Anisotropic Ferromagnetic Spin Chains
We prove the existence of discrete breathers (time-periodic, spatially localized solutions) in weakly coupled ferromagnetic spin chains with easy-axis anisotropy. Using numerical methods we then investigate the continuation of discrete breather solutions as the intersite coupling is increased. We find a band of frequencies for which the 1site breather continues all the way to the soliton soluti...
