On the bound states and correlation functions of a class of Calogero-type quantum many-body problems with balanced loss and gain
Debdeep Sinha, Pijush K. Ghosh
The quantization of many-body systems with balanced loss and gain is investigated. Two types of models characterized by either translational invariance or rotational symmetry under…

Hamiltonian formulation of systems with balanced loss-gain and exactly solvable models
Pijush K. Ghosh, Debdeep Sinha
A Hamiltonian formulation of generic many-body systems with balanced loss and gain is presented. It is shown that a Hamiltonian formulation is possible only if the balancing of los…

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…
