We investigate the dynamical behavior of a symmetric linear coupling of three quadratic maps with exponential terms, and identify various interesting features as a function of two control parameters. In particular, we...
Porous silicon is a nanostructured material and exhibits efficient photo- and electro-luminescence in the visible range at room temperature, as well as a tunable refractive index determined by its porosity. Porous sil...
Dynamic behaviors of the erbium-doped fiber laser (EDFL) with dual-frequency loss modulation are experimentally investigated. Frequency-locked states with their winding numbers which form the devil's staircase are ...

In this paper, we report the dynamical behaviours of a four-dimenslonal autonomous continuous dissipative system analysed when the parameter is varied in the range we are interested in. The system changes its dynamica...
A simulation model and the dynamics of the forced modulation doped heterostructure, which operates in the state far from thermodynamic equilibrium, are discussed. The numerical simulations clearly reveal that the sys...
