Replica symmetry breaking in specially designed TiO nanoparticles-based dye-colloidal random laser
Pablo I. R. Pincheira, Andréa F. Silva, Sandra J. M. Carreño +5
By using specially designed nanoparticles scatterers which prevents photodegradation of the dye, we present clear demonstration of replica symmetry break and a photonic paramagneti…
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…
Stochastic Bifurcations induced by correlated Noise in a Birhythmic van der Pol System
R. Mbakob Yonkeu, R. Yamapi, G. Filatrella +1
We investigate the effects of exponentially correlated noise on birhythmic van der Pol type oscillators. The analytical results are obtained applying the quasi-harmonic assumption…
Global Dynamics for the coupled Einstein-Maxwell system with pseudo-tensor of pressure on Bianchi spacetimes
Norbert Noutchegueme, Eric Magloire Zangue
Global existence to the coupled Einstein-Maxwell system which rules the dynamics of a kind of charged matter with a pseudo-tensor of pressure is proved, in Bianchi I-VIII spacetime…
Random lasers, Lévy statistics and spin glasses: Synergy between photonics and complex systems
Anderson S. L. Gomes, Ernesto P. Raposo, André L. Moura +5
Random lasers have been recently approached as a photonic platform for disordered complex systems, such as spin glasses. In this work, using a Nd:YBO random laser system…
Localized modulated wave solutions in diffusive glucose-insulin systems
Alain Mvogo, Antoine Tambue, Germain Hubert Ben-Bolie +1
We investigate intercellular insulin dynamics in an array of diffusively coupled pancreatic islet \b{eta}-cells. The cells are connected via gap junction coupling, where nearest ne…
