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…
Non-Lagrangian approach for coupled complex Ginzburg-Landau systems with higher order-dispersion
Roger Bertin Djob, Aurelien Kenfact-Jiotsa, A. Govindarajan
It is known that after a particular distance of evolution in fiber lasers, two (input) asymmetric soliton like pulses emerge as two (output) symmetric pulses having same and consta…
Phase transitions in quantum tunneling and quasi-exact solvability for a family of parametric double-well potentials
F. Naha Nzoupe, Alain M. Dikande, C. Tchawoua
A parametrized double-well potential is proposed to address the issue of the impact of shape deformability of some bistable physical systems, on their quantum dynamics and classica…
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…
Optimal intervention strategies of staged progression HIV infections through an age-structured model with probabilities of ART drop out
Mboya Ba, Ramsès Djidjou-Demasse, Mountaga Lam +1
In this paper, we construct a model to describe the transmission of HIV in a homogeneous host population. By considering the specific mechanism of HIV, we derive a model structured…
