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…
Supersymmetric Many-particle Quantum Systems with Inverse-square Interactions
Pijush K. Ghosh
The development in the study of supersymmetric many-particle quantum systems with inverse-square interactions is reviewed. The main emphasis is on quantum systems with dynamical OS…
Deconstructing non-dissipative non-Dirac-hermitian relativistic quantum systems
Pijush K. Ghosh
A method to construct non-dissipative non-Dirac-hermitian relativistic quantum system that is isospectral with a Dirac-hermitian Hamiltonian is presented. The general technique inv…
Deconstructing non-Dirac-hermitian supersymmetric quantum systems
Pijush K. Ghosh
A method to construct non-Dirac-hermitian supersymmetric quantum system that is isospectral with a Dirac-hermitian Hamiltonian is presented. The general technique involves a realiz…
Supersymmetric quantum mechanics on noncommutative space
Pijush K. Ghosh
We construct supersymmetric quantum mechanics in terms of two real supercharges on noncommutative space in arbitrary dimensions. We obtain the exact eigenspectra of the two and thr…
