Quasi normal modes in Schwarzschild-DeSitter spacetime: A simple derivation of the level spacing of the frequencies
T. Roy Choudhury, T. Padmanabhan
It is known that the imaginary parts of the quasi normal mode (QNM) frequencies for the Schwarzschild black hole are evenly spaced with a spacing that depends only on the surface g…

Quasi normal modes: A simple derivation of the level spacing of the frequencies
T. Padmanabhan
It is known that the imaginary parts of the frequencies of the quasi normal modes of the Schwarzschild black hole are equally spaced, with the level spacing dependent only on the s…

Role of Horizons in Semiclassical Gravity: Entropy and the Area Spectrum
T. Padmanabhan, Apoorva Patel
In any space-time, it is possible to have a family of observers who have access to only part of the space-time manifold, because of the existence of a horizon. We demand that \emph…
