Time-dependent Monte Carlo simulations of the critical and Lifshitz points of the ANNNI model
Roberto da Silva, Nelson Alves, J. R. Drugowich de Felício
In this work, we study the critical behavior of second order points and specifically of the Lifshitz point (LP) of a three-dimensional Ising model with axial competing interactions…
Towards Rock-paper-scissors patterns in the Optional Public Goods Game under random mobility
Pablo A. Valverde, Roberto da Silva, Eduardo V. Stock
Social dilemmas concern a natural conflict between cooperation and self interests among individuals in large populations. The emergence of cooperation and its maintenance is the ke…
A new look on the stabilization of inverted pendulum with parametric excitation and large random frequencies: analytical and numerical approaches
Roberto da Silva, Sandra D. Prado, Henrique A. Fernandes
In this paper we explore the stability of an inverted pendulum with generalized parametric excitation described by a superposition of sines with different frequencies and phase…
An alternative method to characterize first- and second-order phase transitions in surface reaction models
Henrique A. Fernandes, Roberto da Silva, Eder D. Santos +2
In this work, we revisited the Ziff-Gulari-Barshad (ZGB) model to study its phase transitions and critical exponents through time-dependent Monte Carlo simulations. We used a metho…
