On the Real Spectra of Calogero Model with Complex Coupling
Pijush K. Ghosh, Kumar S. Gupta
We study the eigenvalue problem of the rational Calogero model with the coupling of the inverse-square interaction as a complex number. We show that although this model is manifest…

Super-Calogero model with OSp(2|2) supersymmetry : is the construction unique?
Pijush K. Ghosh
We show that the construction of super-Calogero model with OSp(2|2) supersymmetry is not unique. In particular, we find a new co-ordinate representation of the generators of the OS…

Near-Horizon States of Black Holes and Calogero Models
B Basu-Mallick, Pijush K. Ghosh, Kumar S. Gupta
We find self-adjoint extensions of the rational Calogero model in presence of the harmonic interaction. The corresponding eigenfunctions may describe the near-horizon quantum state…
