Phase transition properties via partition function zeros: The Blume-Capel ferromagnet revisited
Leïla Moueddene, Nikolaos G Fytas, Bertrand Berche
Since the landmark work of Lee and Yang, locating the zeros of the partition function in the complex magnetic-field plane has become a powerful method for studying phase transition…

Critical and tricritical behavior of the Blume-Capel model: Results from small-scale Monte Carlo simulations
Leïla Moueddene, Nikolaos G. Fytas, Bertrand Berche
We investigate the location of the critical and tricritical points of the three-dimensional Blume-Capel model by analyzing the behavior of the first Lee-Yang zero, the density of p…
