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…

`Thermal' ambience and fluctuations in classical field theory
K. Srinivasan, L. Sriramkumar, T. Padmanabhan
A plane monochromatic wave will not appear monochromatic to a noninertial observer. We show that this feature leads to a `thermal' ambience in an accelerated frame {\it even in cla…
