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…
Taming Hamiltonian systems with balanced loss and gain via Lorentz interaction : General results and a case study with Landau Hamiltonian
Pijush K. Ghosh
The kinetic energy term of Hamiltonian systems with balanced loss and gain is not semi-positive-definite, leading to instabilities at the classical as well quantum level. It is sho…
Integrable coupled Linard-type systems with balanced loss and gain
Debdeep Sinha, Pijush K. Ghosh
A Hamiltonian formulation of generic many-particle systems with space-dependent balanced loss and gain coefficients is presented. It is shown that the balancing of loss and gain ne…
PT -symmetric rational Calogero model with balanced loss and gain
Debdeep Sinha, Pijush K. Ghosh
A two body rational Calogero model with balanced loss and gain is investigated. The system yields a Hamiltonian which is symmetric under the combined operation of parity (P) and ti…
