On the evaluation of magnetisation fluctuations with Q2R cellular automata
Cristian Fernando Moukarzel, Néstor Parga · Journal of Physics A Mathematical and General · 1989
The authors discuss the evaluation of fluctuations with the Q2R cellular automata. Explicit calculations are performed for the two-dimensional case. They argue that when Q2R results are compared properly with Monte Carlo simulations there are no inconsistencies at low temperatures as claimed recently.
