The effect of long-range interactions on the dynamics and statistics of 1D Hamiltonian lattices with on-site potential
H. Christodoulidi, T. Bountis, L. Drossos
We examine the role of long--range interactions on the dynamical and statistical properties of two 1D lattices with on--site potentials that are known to support discrete breathers…
Dynamics and Statistics of the Fermi--Pasta--Ulam --model with different ranges of particle interactions
Helen Christodoulidi, Tassos Bountis, Constantino Tsallis +1
In the present work we study the Fermi--Pasta--Ulam (FPU) --model involving long--range interactions (LRI) in both the quadratic and quartic potentials, by introducing two indep…
Numerical integration of variational equations for Hamiltonian systems with long range interactions
Helen Christodoulidi, Tassos Bountis, Lambros Drossos
We study numerically classical 1-dimensional Hamiltonian lattices involving inter-particle long range interactions that decay with distance like 1/r^alpha, for alpha>=0. We demonst…
Coupled symplectic maps as models for subdiffusive processes in disordered Hamiltonian lattices
Chris G. Antonopoulos, Tassos Bountis, Lambros Drossos
We investigate dynamically and statistically diffusive motion in a chain of linearly coupled 2-dimensional symplectic McMillan maps and find evidence of subdiffusion in weakly and…
Complex Statistics and Diffusion in Nonlinear Disordered Particle Chains
Ch. G. Antonopoulos, T. Bountis, Ch. Skokos +1
We investigate dynamically and statistically diffusive motion in a Klein-Gordon particle chain in the presence of disorder. In particular, we examine a low energy (subdiffusive) an…
