Hawking radiation in different coordinate settings: Complex paths approach
S. Shankaranarayanan, T. Padmanabhan, K. Srinivasan
We apply the technique of complex paths to obtain Hawking radiation in different coordinate representations of the Schwarzschild space-time. The coordinate representations we consi…
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…
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…
Particle production and complex path analysis
K. Srinivasan, T. Padmanabhan
This paper discusses particle production in Schwarzchild-like spacetimes and in an uniform electric field. Both problems are approached using the method of complex path analysis. P…
Facets of Tunneling: Particle production in external fields
K. Srinivasan, T. Padmanabhan
This paper presents a critical review of particle production in an uniform electric field and Schwarzchild-like spacetimes. Both problems can be reduced to solving an effective one…
A formal analysis of two dimensional gravity
S. Engineer, K. Srinivasan, T. Padmanabhan
Several investigations in the study of cosmological structure formation use numerical simulations in both two and three dimensions. In this paper we address the subtle question of…
