Stochastic birhythmicity outside the coexistence region in the Hindmarsh-Rose model
Ignacio Ortega-Piwonka, Javier Used, Jesus M. Seoane +1
In this work, we demonstrate that the Hindmarsh-Rose model subjected to additive white noise exhibits birhythmicity. Specifically, the system fluctuates between two distinct bursti…
Fractional damping enhances chaos in the nonlinear Helmholtz oscillator
Adolfo Ortiz, Jianhua Yang, Mattia Coccolo +2
The main purpose of this paper is to study both the underdamped and the overdamped dynamics of the nonlinear Helmholtz oscillator with a fractional order damping. For that purpose,…
Phase control of escapes in the fractional damped Helmholtz oscillator
Mattia Coccolo, Jesús M. Seoane, Stefano Lenci +1
We analyze the nonlinear Helmholtz oscillator in the presence of fractional damping, a characteristic feature in several physical situations. In our specific scenario, as well as i…
Rotating cluster formations emerge in an ensemble of active particles
Julia Cantisán, Jesús M. Seoane, Miguel A. F. Sanjuán
Rotating clusters or vortices are formations of agents that rotate around a common center. These patterns may be found in very different contexts: from swirling fish to surveillanc…
Rate and memory effects in bifurcation-induced tipping
Julia Cantisán, Serhiy Yanchuk, Jesús M. Seoane +2
A variation in the environment of a system, such as the temperature, the concentration of a chemical solution or the appearance of a magnetic field, may lead to a drift in one of t…
Delay-induced resonance suppresses damping-induced unpredictability
Mattia Coccolo, Julia Cantisán, Jesús M. Seoane +2
Combined effects of the damping and forcing in the underdamped time-delayed Duffing oscillator are considered in this paper. We analyze the generation of a certain damping-induced…
