Inequivalent Quantizations of the Rational Calogero Model
B. Basu-Mallick, Pijush K. Ghosh, Kumar S. Gupta
We show that the rational Calogero model with suitable boundary condition admits quantum states with non-equispaced energy levels. Such a spectrum generically consists of infinitel…
Novel Quantum States of the Rational Calogero Models Without the Confining Interaction
B. Basu-Mallick, Pijush K. Ghosh, Kumar S. Gupta
We show that the N-particle A_{N-1} and B_N rational Calogero models without the harmonic interaction admit a new class of bound and scattering states. These states owe their exist…
Near-Horizon Conformal Structure and Entropy of Schwarzschild Black Holes
Kumar S. Gupta
Near-horizon conformal structure of a massive Schwarzschild black hole of mass M is analyzed using a scalar field as a simple probe of the background geometry. The near-horizon dyn…
Black Hole Decay as Geodesic Motion
Kumar S. Gupta, Siddhartha Sen
We show that a formalism for analyzing the near-horizon conformal symmetry of Schwarzschild black holes using a scalar field probe is capable of describing black hole decay. The eq…
