Phase Transitions and Order Parameters in Correlation Matrices: A Wishart-Ensemble Perspective on the Largest Eigenvalue
Roberto da Silva, Antonio Mihara, Henrique Tramontina +1
We investigate the properties of the largest eigenvalue of correlation matrices within the framework of Wishart ensembles. In this work, we propose the largest eigenvalue as an eff…
Crossover effects on the phase transitions phenomena translated by arborecences and spectral properties
Roberto da Silva
This study investigates how visibility graphs constructed from Monte Carlo Markov Chain time series of spin models capture the critical behavior of the system. More precisely, we s…
Phase Diagrams of the YK Surface-Reaction Model on 2D lattices with Exchange Diffusion
Henrique A. Fernandes, Roberto da Silva, Paulo F. Gomes
In this work, we investigate the phase diagrams of the Yaldram and Khan catalytic surface model on square and hexagonal lattices when exchange diffusion is allowed for carbon monox…
Topology induced modifications in the critical behavior of the Yaldram Khan catalytic reaction model
Paulo F. Gomes, Henrique A. Fernandes, Roberto da Silva
In this work, we investigated how the use of complex networks as catalytic surfaces can affect the phase diagram of the Yaldram-Khan model, as well as how the order of the phase tr…
Unveiling the hidden weak universality of the ZGB model
Henrique Almeida Fernandes, Roberto da Silva
In this work, we revisited the Ziff-Gullari-Barshad (ZGB) model in order to investigate its critical behavior when carbon monoxide (CO) molecules are allowed to desorb from the cat…
Mean-field criticality explained by random matrices theory
Roberto da Silva, Heitor C. Fernandes, Eliseu Venites Filho +2
How a system initially at infinite temperature responds when suddenly placed at finite temperatures is a way to check the existence of phase transitions. It has been shown in [R. d…
