Unsupervised Machine Learning of the Contact Process
L. T. Brito, G. A. Alves, F. W. S. Lima +3
We investigate how unsupervised machine-learning methods can characterize the active-absorbing phase transition in the contact process in one and two spatial dimensions. Our analys…
Supervised and Unsupervised Deep Learning Applied to the Majority Vote Model
J. F. Silva Neto, D. S. M. Alencar, L. T. Brito +5
We employ deep learning techniques to investigate the critical properties of the continuous phase transition in the majority vote model. In addition to deep learning, principal com…
Kinetic Flat-Histogram Simulations of Non-Equilibrium Stochastic Processes with Continuous and Discontinuous Phase Transitions
L. M. C. Alencar, T. F. A. Alves, G. A. Alves +3
As far as we know, there is no flat-histogram algorithm to sample the stationary distribution of non-equilibrium stochastic processes. The present work addresses this gap by introd…
Generalized Diffusive Epidemic Process with Permanent Immunity in Two Dimensions
V. R. Carvalho, T. F. A. Alves, G. A. Alves +4
We introduce the generalized diffusive epidemic process, which is a metapopulation model for an epidemic outbreak where a non-sedentary population of walkers can jump along lattice…
Social dilemmas, network reciprocity and the small-world property
F. B. Pereira, R. S. Ferreira, D. S. M. Alencar +4
We revisit two evolutionary game theory models, namely the Prisoner and the Snowdrift dilemmas, on top of small-world networks. These dynamics on networked populations (individuals…
Critical Short-Time Behavior of Majority-Vote Model on Scale-Free Networks
D. S. M. Alencar, J. F. S. Neto, T. F. A. Alves +4
We discuss the short-time behavior of the majority vote dynamics on scale-free networks at the critical threshold. We introduce a heterogeneous mean-field theory on the critical sh…
Estimating thresholds for asynchronous susceptible-infected-removed model on complex networks
D. S. M. Alencar, T. F. A. Alves, F. W. S. Lima +3
We use the pair heterogeneous mean-field (PHMF) approximation for an asynchronous version of the susceptible-infected-removed (SIR) model to estimate the epidemic thresholds on com…
Is Kaniadakis -generalized statistical mechanics general?
T. F. A. Alves, J. F. da Silva Neto, F. W. S. Lima +2
In this Letter we introduce some field-theoretic approach for computing the critical properties of systems undergoing continuous phase transitions governed by the -generalized s…
Droplet Finite-Size Scaling of the Majority Vote Model on Quenched Scale-Free Networks
D. S. M. Alencar, T. F. A. Alves, F. W. S. Lima +3
We consider the Majority Vote model coupled with scale-free networks. Recent works point to a non-universal behavior of the Majority Vote model, where the critical exponents depend…
Epidemic Outbreaks on Quenched Scale-Free Networks
D. S. M. Alencar, T. F. A. Alves, F. W. S. Lima +3
We present a finite-size scaling theory of a contact process with permanent immunity on uncorrelated scale-free networks. We model an epidemic outbreak by an analog of the suscepti…
Phase Diagram of the Contact Process on Barabasi-Albert Networks
D. S. M. Alencar, T. F. A. Alves, G. A. Alves +3
We show results for the contact process on Barabasi networks. The contact process is a model for an epidemic spreading without permanent immunity that has an absorbing state. For f…
Asynchronous SIR model on Two-Dimensional Quasiperiodic Lattices
G. B. M. Santos, T. F. A. Alves, G. A. Alves +1
We considered the Asynchronous SIR (susceptible-infected-removed) model on Penrose and Ammann-Beenker quasiperiodic lattices, and obtained its critical behavior by using Newman-Zif…
Critical behavior of the 2D Ising model modulated by the Octonacci sequence
G. A. Alves, M. S. Vasconcelos, T. F. A. Alves
We investigated the Ising model on a square lattice with ferro and antiferromagnetic interactions modulated by the quasiperiodic Octonacci sequence in both directions of the lattic…
