    The reduced phase space formalism for quantising black holes has recently been extended to find the area and angular momentum spectra of four dimensional Kerr black holes. We extend this further to rotating black holes ...
  • Das, Saurya; Dey, Anindya; SenGupta, Soumitra (Arts and ScienceDepartment of PhysicsUniversity of LethbridgeUniversity of Texas at AustinIndian Association for the Cultivation of Science, 2015-12-15)
    We generalise the RS braneworld model by taking into account a general stringy bulk containing the scalar dilaton field and the two-form Kalb-Ramond field, apart from gravity. Assuming small fluctuations around a RS ...

R.; Leonidaki, I.; Xilouris, E.M.; Weiss, A.; Zhang, Z.-Y.; van der Werf, P.; Aalto, S.; Armus, L.; Diaz-Santos, T.; Evans, A.S.; Fischer, J.; Gao, Y.; Gonzalez-Alfonso, E.; Harris, A.; Henkel, C.; Mekjerink, R.; Naylor, David A; Smith, H.A.; Spaans, M.; Stacey, G.J.; Veilleux, S.; Walter, F. (American Astronomical Society, 2014)
    We present FIR[50-300 um]-CO luminosity relations (i.e., log Lfir = a log L’co + B) for the full CO rotational ladder from J = 1 – 0 up to J = 13 -12 for a sample of 62 local (z <= 0.1) (Ultra) Luminous Infrared Galaxies ...

    We show that the existence of a minimum measurable length and the related Generalized Uncertainty Principle (GUP), predicted by theories of Quantum Gravity, influence all quantum Hamiltonians. Thus, they predict quantum ...
  • Das, Saurya; Shankaranarayanan, S. (Arts and ScienceDepartment of PhysicsUniversity of LethbridgeMax-Planck-Institut für Gravitationphysik, 2016-01-06)
    Understanding the area-proportionality of black hole entropy (the ‘Area Law’) from an underlying fundamental theory has been one of the goals of all models of quantum gravity. A key question that one asks is: where are ...
  • Das, Saurya; Shankaranarayanan, S.; Sur, Sourav (Arts and ScienceDepartment of PhysicsUniversity of LethbridgeMax-Planck-Institut für Gravitationphysik, 2015-12-15)
    Considering the entanglement between quantum field degrees of freedom inside and outside the horizon as a plausible source of black hole entropy, we address the question: where are the degrees of freedom that give rise ...
