Aldo Di Biasio - Università degli Studi di Parma # Cooperativity and anticooperativity in chemical kinetics through mean-field models # We consider cooperative reactions and we study the effects of the interaction strength among the system components on the reaction rate, hence realizing a connection between microscopic and macroscopic observables. Our approach is based on statistical mechanics models and it is developed analytically via mean-field techniques. We show that cooperative and anticooperative behaviors naturally emerge from the model when the coupling strength is set to be respectively positive and negative, so that varying a simple effective parameter a plethora of different phenomena are recovered.
