A Microcanonical Inflection Point Analysis via Parametric Curves and its Relation to the Zeros of the Partition Function
Julio Cesar Siqueira Rocha, Rodrigo Alves Dias, Bismarck Vaz da Costa
In statistical physics, phase transitions are arguably among the most extensively studied phenomena. In the computational approach to this field, the development of algorithms capa…
