Abstract:
Until 1951 the dynamic of chaos represented a challenge for the mathematical determinism. The solution for the differential coupled equations was unstable in time; it evolved to a divergent behaviour (logistical equations, biologic rate of population, the meteorological Lorentz equation, etc.).
The Elementary Particles Physics and, especially, the Nuclear Physics at high and very high energies - dominated by fluctuations and multiple types of interaction - need to introduce such stochastic processes. Also, the time representations of the nuclear matter in extreme conditions (like quark-gluon plasma, plasma hadronic and its phase transitions) pointed out the previous remarks.
The goal of this talk is to present preliminary attempts to treat a number of aspects linked to the Nuclear Physics at high energies using the dynamics of chaos.
Three types of analysis were described using dynamics of chaos, namely: (i) evolution of nuclear systems confined in a potential well inspired by billiard game which a Wood-Saxon oscillating barrier; (ii) the quarks system interacting by bi-particle potential for 21 objects; (iii) possible representations of the quark clusters and clusterization adding a geometrical criteria for the production of multi-quark states. A few comparisons with data and other predictions were included, too.
