Moving discrete breathers in a -FPU lattice revisited
H. Duran, J. Cuevas-Maraver, P. G. Kevrekidis +1
In the present work we revisit the existence, stability and dynamical properties of moving discrete breathers in -FPU lattices. On the existence side, we propose a numerical pro…

Unstable dynamics of solitary traveling waves in a lattice with long-range interactions
H. Duran, H. Xu, P. G. Kevrekidis +1
In this work we revisit the existence, stability and dynamics of unstable traveling solitary waves in the context of lattice dynamical systems. We consider a nonlinear lattice of a…
