Localization and equipartition of energy in the β-FPU chain: Chaotic breathers
The evolution towards equipartition in the β-FPU chain is studied considering as initial condition
the highest frequency mode. Above an analytically derived energy threshold, this zone-…

Dynamical phases of the Hindmarsh-Rose neuronal model: Studies of the transition from bursting to spiking chaos
…, A Morelli, R Genesio, A Torcini - Chaos: An Interdisciplinary …, 2007 - pubs.aip.org
The dynamical phases of the Hindmarsh-Rose neuronal model are analyzed in detail by
varying the external current I. For increasing current values, the model exhibits a peculiar …
