Interplay of coupling and forcing: Coherence in a nonlinear delayed oscillator
Mattia Coccolo, Miguel A. F. Sanjuán
Coupled oscillators often experience two distinct influences: an internal input transmitted through coupling from a driver subsystem, and an external periodic forcing applied direc…
Grünwald--Letnikov Memory Truncation in a Fractional Duffing Oscillator: Coherence Loss and Effective Delay Complexity
Mattia Coccolo
We investigate the dynamical and analytical consequences of truncating the Grünwald--Letnikov memory term in a fractional Duffing oscillator. The truncated memory is treated not me…
Transmitted and Storage-Dominated Resonance in Fractionally Damped Unidirectionally Coupled Duffing Oscillators
Messali Rouaida, Mattia Coccolo, Miguel A. F. Sanjuán
This paper investigates resonance transmission in two unidirectionally coupled Duffing oscillators with fractional damping, where the driver is harmonically forced and the receiver…
High-frequency tuning of internal resonance and targeted energy transfer in a Van der Pol oscillator coupled to a nonlinear energy sink
Somnath Roy, Mattia Coccolo, Sayan Gupta +1
Targeted energy transfer (TET) from a Van der Pol oscillator coupled to a nonlinear energy sink (NES) is investigated under the action of a high-frequency external drive, which tun…
Collective vibrational resonance and mode selection in nonlinear resonator arrays
Somnath Roy, Mattia Coccolo, Anirban Ray +1
This article investigates how a uniform high frequency (HF) drive applied to each site of a weakly-coupled discrete nonlinear resonator array can modulate the onsite natural stiffn…
When a periodic forcing and a time-delayed nonlinear forcing drive a non-delayed Duffing oscillator
Mattia Coccolo, Miguel A. F. Sanjuán
When two systems are coupled, the driver system can function as an external forcing over the driven or response system. Also, an external forcing can independently perturb the driv…
Parametric Autoresonance with Time-Delayed Control

We investigate how a constant time delay influences a parametric autoresonant system. This is a nonlinear system driven by a parametrically chirped force with a negative delay-feed…
Vibrational resonance in the FitzHugh-Nagumo neuron model under state-dependent time delay
M. Siewe Siewe, S. Rajasekar, Mattia Coccolo +1
We propose a nonlinear one-dimensional FitzHugh--Nagumo neuronal model with an asymmetric potential driven by both a high-frequency and a low-frequency signal. Our numerical analys…
Transmitted resonance in a coupled system
Mattia Coccolo, Miguel A. F. Sanjuán
When two systems are coupled, one can play the role of the driver, and the other can be the driven or response system. In this scenario, the driver system can behave as an external…
Fractional damping enhances chaos in the nonlinear Helmholtz oscillator
