Period in the chaotic phase of Q2R automata

More than 1000 h on a high-speed special computer were used to analyse the global limit cycle period of the Q2R automata in 2D at various energies. An exponential increase of the periods with system size N was found even at energies below the Curie temperature. Even for T to infinity , i.e. in the fully chaotic regime, the paramagnetic phase of Q2R was found to be non-ergodic.
