Hyperacceleration in a stochastic Fermi-Ulam model
A. K. Karlis, P. K. Papachristou, F. K. Diakonos +2
Fermi acceleration in a Fermi-Ulam model, consisting of an ensemble of particles bouncing between two, infinitely heavy, stochastically oscillating hard walls, is investigated. It…

Lyapunov Instability versus Relaxation Time in two Coupled Oscillators
P. K. Papachristou, E. Mavrommatis, V. Constantoudis +2
We consider the relation between relaxation time and the largest Lyapunov exponent in a system of two coupled oscillators, one of them being harmonic. It has been found that in a r…
