Generation of CMB and Cosmological constant via bulk viscosity
Sanved Kolekar, S. Shankaranarayanan, S. M. Chitre
A simple model of uniformly expanding, homogeneous Universe with a bulk viscosity is studied wherein the inflationary density decays due to viscous dissipation during the expansion…
Galileon scalar electrodynamics
Ashu Kushwaha, S. Shankaranarayanan
We construct a consistent model of Galileon scalar electrodynamics. The model satisfies three essential requirements: (1) The action contains higher-order derivative terms, and obe…
Microscopic Model building for Black Hole Membranes from Constraints of Symmetry
Swastik Bhattacharya, S. Shankaranarayanan
Einstein equations projected on black-hole horizons give rise to the equations of motion of a viscous fluid. This suggests a way to understand the microscopic degrees of freedom on…
Polymer quantization and advanced gravitational wave detector
D. Jaffino Stargen, S. Shankaranarayanan, Saurya Das
We investigate the observable consequences of Planck scale effects in the advanced gravitational wave detector by polymer quantizing the optical field in the arms of the interferom…
Strong gravity signatures in the polarization of gravitational waves
S. Shankaranarayanan
General Relativity is a hugely successful description of gravitation. However, both theory and observations suggest that General Relativity might have significant classical and qua…
Low-energy modified gravity signatures on the large-scale structures
Joseph P Johnson, S. Shankaranarayanan
A large number of dark energy and modified gravity models lead to the same expansion history of the Universe, hence, making it difficult to distinguish them from observations. To m…
