Stability Properties of 1-Dimensional Hamiltonian Lattices with Non-analytic Potentials
Anastasios Bountis, Konstantinos Kaloudis, Thomas Oikonomou +2
We investigate the local and global dynamics of two 1-Dimensional (1D) Hamiltonian lattices whose inter-particle forces are derived from non-analytic potentials. In particular, we…
Chaotic dynamics of graphene and graphene nanoribbons
Malcolm Hillebrand, Bertin Many Manda, George Kalosakas +2
We study the chaotic dynamics of graphene structures, considering both a periodic, defect free, graphene sheet and graphene nanoribbons (GNRs) of various widths. By numerically cal…
Orbit classification and networks of periodic orbits in the planar circular restricted five-body problem
Euaggelos E. Zotos, K. E. Papadakis
The aim of this paper is to numerically investigate the orbital dynamics of the circular planar restricted problem of five bodies. By numerically integrating several large sets of…
Heterogeneity and chaos in the Peyrard-Bishop-Dauxois DNA model
Malcolm Hillebrand, George Kalosakas, Adrian Schwellnus +1
We discuss the effect of heterogeneity on the chaotic properties of the Peyrard-Bishop-Dauxois nonlinear model of DNA. Results are presented for the maximum Lyapunov exponent and t…
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…
