This work studies the nonlinear dynamics and passive control of chemical oscillations governed by a forced modified Van der Pol–Duffing oscillator. We considered the dynamics of nonlinear chemical systems subjected to fluctuating hydrodynamic drag fo [...]
This paper addresses the issue of a mixed Rayleigh–Liénard oscillator with external and parametric periodic-excitations. The Melnikov method is utilized to analytically determine the domain boundaries where horseshoe chaos appears. Routes to chaos ar [...]

Spin-crossover (SCO) and Prussian blue analogs (PBAs) materials are investigated in 2D with a three-state Blume–Emery–Griffiths (BEG) model where each spin interacts with its nearest neighbors (nn) and may be either in high-spin (HS) or low-spin ( [...]
