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…
The number of spanning trees as an indicator of critical phenomena: When Kirchhoff meets Ising
Roberto da Silva, Henrique A. Fernandes, Paulo G. Freitas +3
Visibility graphs are spatial interpretations of time series. When derived from the time evolution of physical systems, the graphs associated with such series may exhibit propertie…
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…
Revisiting the Contact Model with Diffusion Beyond the Conventional Methods
Roberto da Silva, Eliseu Venites Filho, Henrique Almeida Fernandes +1
The contact process is a non-equilibrium Hamiltonian model that, even in one dimension, lacks an exact solution and has been extensively studied via Monte Carlo simulations, both i…
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…
