Geometric Finiteness, Holography and Quasinormal Modes for the Warped AdS_3 Black Hole
Kumar S. Gupta, E. Harikumar, Siddhartha Sen +1
We show that there exists a precise kinematical notion of holography for the Euclidean warped black hole. This follows from the fact that the Euclidean warped black…
Constraints on the quantum gravity scale from kappa - Minkowski spacetime
A. Borowiec, Kumar S. Gupta, S. Meljanac +1
We compare two versions of deformed dispersion relations (energy vs momenta and momenta vs energy) and the corresponding time delay up to the second order accuracy in the quantum g…
Deformed Oscillator Algebras and QFT in -Minkowski Spacetime
T. R. Govindarajan, Kumar S. Gupta, E. Harikumar +2
In this paper we study the deformed statistics and oscillator algebras of quantum fields defined in -Minkowski spacetime. The twisted flip operator obtained from the twist assoc…
Scalar field dynamics in warped AdS_3 black hole background
Sayan K. Chakrabarti, Pulak Ranjan Giri, Kumar S. Gupta
We study the normal modes of a scalar field in the background of a warped AdS_3 black hole which arises in topologically massive gravity. We discuss the normal mode spectrum using…
