-symmetric ladders with a scattering core
Jennie D'Ambroise, Stefano Lepri, Boris A. Malomed +1
We consider a -symmetric chain (ladder-shaped) system governed by the discrete nonlinear Schrödinger equation where the cubic nonlinearity is carried solely by two ce…
Eigenstates and instabilities of chains with embedded defects
J. D'Ambroise, P. G. Kevrekidis, S. Lepri
We consider the eigenvalue problem for one-dimensional linear Schrödinger lattices (tight-binding) with an embedded few-sites linear or nonlinear, Hamiltonian or non-conservative d…
Pattern formation and localization in the forced-damped FPU lattice
Ramaz Khomeriki, Stefano Lepri, Stefano Ruffo
We study spatial pattern formation and energy localization in the dynamics of an anharmonic chain with quadratic and quartic intersite potential subject to an optical, sinusoidally…
