REGULARITY AND CHAOS IN VLASOV EVOLUTION OF NUCLEAR-MATTER

In this work we perform an analysis of the onset of chaos in mean-fiel d dynamics in the presence of volume instabilities. As a main finding, we show that the mean-field evolution presents two different regimes: a first one dominated by the almost decoupled amplification of severa l collective unstable modes, leading to the early condensation of the system into clusters, which is followed by a second stage dominated by a coalescence mechanism among the large-density domains. Finally we s how that, even at the latest stage considered, chaos does not appear a s fully developed since a hierarchy of the different unstable modes, i nherited from the initial regular amplification of instabilities, rema ins.
