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…
Solvable Limits of a class of generalized Vector Nonlocal Nonlinear Schrödinger equation with balanced loss-gain
Supriyo Ghosh, Pijush K. Ghosh
We consider a class of one dimensional Vector Nonlocal Non-linear Schrödinger Equation (VNNLSE) in an external complex potential with time-modulated Balanced Loss-Gain(BLG) and Lin…
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(…
Non-linear Schrdinger equation with time-dependent balanced loss-gain and space-time modulated non-linear interaction
Supriyo Ghosh, Pijush K. Ghosh
We consider a class of one dimensional vector Non-linear Schrdinger Equation(NLSE) in an external complex potential with Balanced Loss-Gain(BLG) and Linear Coupling(LC) a…
Classical Hamiltonian Systems with Balanced loss and gain
Pijush K Ghosh
Classical Hamiltonian systems with balanced loss and gain are considered in this review. A generic Hamiltonian formulation for systems with space-dependent balanced loss and gain i…
Constructing Solvable Models of Vector Non-linear Schrodinger Equation with Balanced Loss and Gain via Non-unitary transformation
Pijush K Ghosh
We consider vector Non-linear Schrodinger Equation(NLSE) with balanced loss-gain(BLG), linear coupling(LC) and a general form of cubic nonlinearity. We use a non-unitary transforma…
