12 Dec 2017 | | Abstract: | In [1] we presented a Chaos Many-Body Engine toy-model for chaos analysis of
nuclear relativistic collisions at 4.5 A GeV/c (the SKM 200 collaboration),
which was later developed and tested [2] on Cu-Cu collisions at the maximum BNL
energy. Starting from the existing quark billiard models, the main goal of this
work was to extend CMBE to relativistic quark many-body systems. Thus, we first
implemented a confinement algorithm based on two intuitive assumptions: the
bi-particle force is restricted to each elementary white quark cluster
(interaction saturation), and the white clusters configuration of a quark
system conforms to the minimum potential energy requirement. As interaction
retardation is expected to play an important role in chaos analysis of
relativistic many-body systems, we also implemented a Euler retarded algorithm,
and we tested it on a simple two-body gravitational-like system. A first
comparative study suggests that interaction retardation might contribute to the
Virial theorem anomalies encountered for clusters of galaxies. Thus, for the
previously described system, we noticed the Virial coefficient is sub unitary
and tends to one with the growth of interaction velocity. On the other hand,
the time reverse functionality implemented in CMBE v03 could be used together
with retardation for studying the Loschmidt paradox. It is important to mention
also that the new features complexity revealed the necessity of refactoring the
existing code to SOLID. The possibility of providing unit tests is another
benefit of the new application design. In this context, we wrote more than one
hundred automatic tests which are an important indicator of application logic
validity. | | Source: | arXiv, 1712.4230 | | Services: | Forum | Review | PDF | Favorites | |
