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…
Symmetry effects on the static and dynamic properties of coupled magnetic oscillators
J P. Patchett, M. Drouhin, J. W. Liao +7
The effect of symmetry on the resonance spectra of antiferromagnetically coupled oscillators has attracted new interest with the discovery of symmetry-breaking induced anti-crossin…
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.…
Localized exact solutions of symmetric nonlinear Schrödinger equation with space and time modulated nonlinearities
L. E. Arroyo Meza, M. B. Hott, A. de Souza Dutra +1
Using canonical transformations we obtain localized (in space) exact solutions of the nonlinear Schrödinger equation (NLSE) with space and time modulated nonlinearity and in the pr…
Noncommutative oscillator, symmetry and Landau problem
Pulak Ranjan Giri, P. Roy
Isotropic oscillator on a plane is discussed where both the coordinate and momentum space are considered to be noncommutative. We also discuss the symmetry properties of the oscill…
