Gravity as an emergent phenomenon: A conceptual description
T. Padmanabhan
I describe several broad features of a programme to understand gravity as an emergent, long wavelength, phenomenon (like elasticity) and discuss one concrete framework for realizin…
Einstein's equations as a thermodynamic identity: The cases of stationary axisymmetric horizons and evolving spherically symmetric horizons
Dawood Kothawala, Sudipta Sarkar, T. Padmanabhan
There is an intriguing analogy between the gravitational dynamics of the horizons and thermodynamics. In case of general relativity, as well as for a wider class of Lanczos-Loveloc…
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…
A novel approach to particle production in an uniform electric field
K. Srinivasan, T. Padmanabhan
We outline a different method of describing scalar field particle production in a uniform electric field. In the standard approach, the (analytically continued) harmonic oscillator…
The classical essence of black hole radiation
M. Nouri-Zonoz, T. Padmanabhan
We show that the mathematics of Hawking process can be interpreted classically as the Fourier analysis of an exponentially redshifted wave mode which scatters off the black hole an…
Doing it with Mirrors: Classical analogues for Black Hole radiation
K. Srinivasan, T. Padmanabhan
We construct analogues for the quantum phenomena of black hole radiation in the context of {\it classical field theory}. Hawking radiation from a (radially) collapsing star is math…
