Connecting the Unstable Region of the Entropy to the Pattern of the Fisher's Zeros Map
J. C. S. Rocha, B. V. Costa
Phase transitions are one of the most interesting natural phenomena. For finite systems, one of the concerns in the topic is how to classify a specific transition as being of first…
Using the Energy probability distribution zeros to obtain the critical properties of the two-dimensional anisotropic Heisenberg model
Gabriel Bruno Garcia de Souza, Bismarck Vaz da Costa
In this paper we present a Monte Carlo study of the critical behavior of the easy axis anisotropic Heisenberg spin model in two dimensions. Based on the partial knowledge of the ze…
Pushing the limits of EPD zeros method
R. G. M. Rodrigues, B. V. Costa, L. A. S. Mól
The use of partition function zeros in the study of phase transition is growing in the last decade mainly due to improved numerical methods as well as novel formulations and analys…
Phase Diagram of Flexible Polymers with Quenched Disordered Charged Monomers
B. B. Rodrigues, J. C. S. Rocha, B. V. Costa
Recent advances in Generalized Ensemble simulations and microcanonical analysis allowed the investigation of structural transitions in polymer models over a broad range of local be…
Correlations in a polymeric structure immersed in a magnetic solution
B. V. Costa
Polymers are among the most important materials in the modern society being found almost in every activity of our daily life. Understanding their chemical and physical properties l…
Vortices in Kekulene Molecules
Lucas Menicucci, Francisco César Sá Barreto, Bismarck vaz da Costa
Kekulene is an aromatic hydrocarbon with formula C48H24 arranged in the shape of a closed super-ring as shown in Fig. 2. It consists of a sublattice with 48 C atoms with spin 5/2 a…
