Detection of signals in presence of noise through Josephson junction switching currents
O. V. Pountougnigni, R. Yamapi, C. Tchawoua +2
Josephson junctions can be employed to reveal a sinusoidal signal in presence of Gaussian noise. To mimic realistic setups, the detection is performed linearly ramping the bias cur…
Coherence and stochastic resonances in a noisy van der Pol-type circadian pacemaker model driven by light
F. L. Tsafack Tayong, R. Yamapi, G. Filatrella
Daylight plays a major role in the wake/sleep cycle in humans. Indeed, the wake/sleep system stems from biological systems that follow a circadian rhythm determined by the light/da…
Entrainment of a van der Pol-type circadian pacemaker to daylight cycle
F. L. Tsafack Tayong, R. Yamapi, G. Filatrella
A van der Pol self sustained oscillator with higher order nonlinearity exhibits a rich dynamics, with multiple periodic attractors, and still the model allows analytical approximat…
Can Lèvy noise induce coherence and stochastic resonances in a birhythmic van der Pol system?
R. Mbakob Yonkeu, R. Yamapi, G. Filatrella +1
The analysis of a birhythmic modified van der Pol type oscillator driven by periodic excitation and Lèvy noise shows the possible occurrence of coherence resonance and stochastic r…
Lévy noise induced transitions and enhanced stability in a birhythmic van der Pol system
René Yamapi, Raoul Mbakob Yonkeu, Giovanni Filatrella +1
This work describes the effects of Lévy noise on a birhythmic van der Pol like oscillator. Numerical simulations demonstrate that the noise induced escapes from an attractor to ano…
Noise and disorder effects in a series of birhythmic Josephson junctions coupled to a resonator
O. V. Pountougnigni, r. Yamapi, G. Filatrella +1
This paper deal the effects of uncorrelated white noise, in a serie of Josephson Junctions coupled to a linear resonator. The junction are hysteretic, and hence can be consid…
