Synchronization through frequency shuffling

M Aravind, V Pachaulee, M Sarkar, I Tiwari, S Gupta… - Physical Review E, 2024 - APS
A wide variety of engineered and natural systems are modeled as networks of coupled
nonlinear oscillators. In nature, the intrinsic frequencies of these oscillators are not constant …

Critical behavior of noise-induced phase synchronization

PD Pinto, ALA Penna, FA Oliveira - Europhysics Letters, 2017 - iopscience.iop.org
We present for the first time in detail the set of the main critical exponents associated with the
phase transition of the Kuramoto model under multiplicative noise action. This was done …

Pattern transitions and complexity for a nonlocal logistic map

FV Barbosa, AAL Penna, RMS Ferreira… - Physica A: Statistical …, 2017 - Elsevier
We examine the pattern solutions in a generalized nonlocal logistic map that includes
spatial kernels in both growth and competition terms. We show that this map includes as a …

Nonlocal pattern formation effects in evolutionary population dynamics

OT Aranda, ALA Penna, FA Oliveira - Physica A: Statistical Mechanics and …, 2021 - Elsevier
In this work, we derive a deterministic equation for a generalized nonlocal population
dynamics that depends fundamentally on two lengths parameters (α, β). We associate these …
