Analysis of earlier times and flux of entropy on the majority voter model with diffusion
Silva, Roberto da; Oliveira, Mário José de; Tomé, Tânia; Felício, José Roberto Drugovich de (2020) [Artigo de periódico]We study the properties of nonequilibrium systems modelled as spin models without defined Hamiltonian as the majority voter model. This model has transition probabilities that do not satisfy the condition of detailed ... -
A connection between the ice-type model of Linus Pauling and the three-color problem
Silva, Roberto da; Nakao, Osvaldo Shigueru; Felício, José Roberto Drugovich de (2021) [Artigo de periódico]The ice-type model proposed by Linus Pauling to explain its entropy at low temperatures is here approached in a didactic way. We first present a theoretically estimated low-temperature entropy and compare it with numerical ... -
Generalized Metropolis dynamics with a generalized master equation : an approach for time-independent and time-dependent Monte Carlo simulations of generalized spin systems
Silva, Roberto da; Felício, José Roberto Drugovich de; Martinez, Alexandre Souto (2012) [Artigo de periódico]The extension of Boltzmann-Gibbs thermostatistics, proposed by Tsallis, introduces an additional parameter q to the inverse temperature β. Here, we show that a previously introduced generalized Metropolis dynamics to evolve ... -
Nonequilibrium critical dynamics of the two-dimensional Ashkin-Teller model at the Baxter line
Fernandes, Henrique Almeida; Silva, Roberto da; Caparica, Álvaro de Almeida; Felício, José Roberto Drugovich de (2017) [Artigo de periódico]We investigate the short-time universal behavior of the two-dimensional Ashkin-Teller model at the Baxter line by performing time-dependent Monte Carlo simulations. First, as preparatory results, we obtain the critical ... -
Nonequilibrium scaling explorations on a two-dimensional Z(5)-symmetric model
Silva, Roberto da; Fernandes, Henrique Almeida; Felício, José Roberto Drugovich de (2014) [Artigo de periódico]We have investigated the dynamic critical behavior of the two-dimensional Z(5)-symmetric spin model by using short-time Monte Carlo (MC) simulations. We have obtained estimates of some critical points in its rich phase ... -
Time-dependent Monte Carlo simulations of critical and Lifshitz points of the axial-next-nearest-neighbor Ising model
Silva, Roberto da; Alves Junior, Nelson; Felício, José Roberto Drugovich de (2013) [Artigo de periódico]In this work, we study the critical behavior of second-order points, specifically the Lifshitz point (LP) of a three-dimensional Ising model with axial competing interactions [the axial-next-nearest-neighbor Ising (ANNNI) ...
