On the response of non-linearly coupled, accelerated detectors in odd-dimensional flat spacetimes
L. Sriramkumar
In this note, we consider the response of a uniformly accelerated monopole detector that is coupled non-linearly to the nth power of a quantum scalar field in (D+1)-dimensional fla…

Will small particles exhibit Brownian motion in the quantum vacuum?
Gilad Gour, L. Sriramkumar
The Brownian motion of small particles interacting with a field at a finite temperature is a well-known and well-understood phenomenon. At zero temperature, even though the thermal…

`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…
