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…
Amplitude Stochastic Response of Rayleigh Beams to Randomly Moving Loads
L. M. Anague Tabejieu, B. R. Nana Nbendjo, G. Filatrella +1
We consider the problem of the nonlinear response of a Rayleigh beam to the passage of a train of forces moving with stochastic velocity. The Fourier transform and the theory of re…
Pseudopotential of birhythmic van der Pol type systems with correlated noise
R. Mbakob Yonkeu, R. Yamapi, G. Filatrella +1
We propose to compute the effective activation energy, usually referred to a pseudopotential or quasipotential, of a birhythmic system -- a van der Pol like oscillator -- in the pr…
Noise Effects on birhythmic Josephson Junction coupled to a Resonator
R. Yamapi, G. Filatrella
We study the effect of noise on a Josephson junction that, coupled to a linear resonator, can oscillate at two frequencies. To establish the global stability of the attractor…
Escape Time of Josephson Junctions for Signal Detection
P. Addesso, G. Filatrella, V. Pierro
In this Chapter we investigate with the methods of signal detection the response of a Josephson junction to a perturbation to decide if the perturbation contains a coherent oscilla…
Escape Time Characterization of Pendular Fabry-Perot
P. Addesso, V. Pierro, G. Filatrella
We show that an escape from the potential minimum of Fabry-Perot interferometers can be detected measuring the associated sudden change of reflectivity. We demonstrate that the los…
Effective Fokker-Planck Equation for Birhythmic Modified van der Pol Oscillator
R. Yamapi, G. Filatrella, M. A. Aziz-Alaoui +1
We present an explicit solution based on the phase-amplitude approximation of the Fokker-Planck equation associated with the Langevin equation of the birhythmic modified van der Po…
Global stability analysis of birhythmicity in a self-sustained oscillator
R. Yamapi, G. Filatrella, M. A. Aziz-Aloui
We analyze global stability properties of birhythmicity in a self-sustained system with random excitations. The model is a multi-limit cycles variation of the van der Pol oscillato…
Stability of the synchronization manifold in nearest neighbors non identical van der Pol-like oscillators
R. Yamapi, H. G. Enjieu Kadji, G. Filatrella
We investigate the stability of the synchronization manifold in a ring and an open-ended chain of nearest neighbors coupled self-sustained systems, each self-sustained system consi…
