Moving mirrors and the fluctuation-dissipation theorem

D. Jaffino Stargen, Dawood Kothawala, L. Sriramkumar

We investigate the random motion of a mirror in (1 + 1)-dimensions that is immersed in a thermal bath of massless scalar particles which are interacting with the mirror through a b…

Quantum gravitational corrections to the propagator in spacetimes with constant curvature

Dawood Kothawala, S. Shankaranarayanan, L. Sriramkumar

The existence of a minimal and fundamental length scale, say, the Planck length, is a characteristic feature of almost all the models of quantum gravity. The presence of the fundam…

Path integral duality modified propagators in spacetimes with constant curvature

Dawood Kothawala, L. Sriramkumar, S. Shankaranarayanan +1

The hypothesis of path integral duality provides a prescription to evaluate the propagator of a free, quantum scalar field in a given classical background, taking into account the…

Quantum gravitational corrections to the stress-energy tensor around the rotating BTZ black hole

Dawood A. Kothawala, S. Shankaranarayanan, L. Sriramkumar

Modes emerging out of a collapsing black hole are red-shifted to such an extent that Hawking radiation at future null infinity consists of modes that have energies beyond the Planc…

Path integral duality and Planck scale corrections to the primordial spectrum in exponential inflation

L. Sriramkumar, S. Shankaranarayanan

The enormous red-shifting of the modes during the inflationary epoch suggests that physics at the Planck scale may modify the standard, nearly, scale-invariant, primordial, density…

Planck scale effects and the suppression of power on the large scales in the primordial spectrum

S. Shankaranarayanan, L. Sriramkumar

The enormous red-shifting of the modes during the inflationary epoch suggests that physics at the very high energy scales may modify the primordial perturbation spectrum. Therefore…
