Chaotic behavior in classical Yang-Mills dynamics


Journal Article

Understanding the underlying mechanisms causing rapid thermalization deduced for high-energy heavy ion collisions is still a challenge. To estimate the thermalization time, entropy growth for classical Yang-Mills theories is studied, based on the determination of Lyapunov exponents. Distinct regimes for short, medium and long sampling times are characterized by different properties of their spectrum of Lyapunov exponents. Clarifying the existence of these regimes and their implications for gauge-field dynamics is one of the results of this article. As a phenomenological application we conclude that for pure gauge theories with random initial conditions thermalization occurs within a few fm/c, an estimate which can be reduced by the inclusion of fermions, specific initial conditions, etc. © 2010 The American Physical Society.
