Balanced loss-gain induced chaos in a periodic Toda lattice
Puspendu Roy, Pijush K. Ghosh
We consider equal-mass periodic Toda oscillators with balanced loss-gain for two and three particles. The two-particle system is integrable with the Hamiltonian and the genralized…

Complex dynamical properties of coupled Van der Pol-Duffing oscillators with balanced loss and gain
Puspendu Roy, Pijush K. Ghosh
We consider a Hamiltonian system of coupled Van der Pol-Duffing(VdPD) oscillators with balanced loss and gain. The system is analyzed perturbatively by using Renormalization Group(…

On regular and chaotic dynamics of a non--symmetric Hamiltonian system of a coupled Duffing oscillator with balanced loss and gain
Pijush K. Ghosh, Puspendu Roy
A non--symmetric Hamiltonian system of a Duffing oscillator coupled to an anti-damped oscillator with a variable angular frequency is shown to admit periodic solutions.…
