Einstein or Jordan: seeking answers from the reheating constraints
Debottam Nandi, Pankaj Saha
Distinguishing conformally coupled frames from the tree-level perturbative observables (scalar spectral index and tensor-to-scalar ratio ) is challenging in cosmolog…
Can non-minimal coupling restore the consistency condition in bouncing universes?
Debottam Nandi, L. Sriramkumar
An important property of the three-point functions generated in the early universe is the so-called consistency condition. According to the condition, in the squeezed limit wherein…
Note on stability in conformally connected frames
Debottam Nandi
Dynamics in conformally connected frames are often referred to as 'equivalent'. In the context of cosmology, while the perturbations remain invariant for a single scalar field mode…
B-Mode auto-bispectrum due to matter bounce
Rahul Kothari, Debottam Nandi
Primordial Gravitational waves leave polarization imprints on the Cosmic Microwave Background (CMB). In this article, we investigate polarization bispectrum, which is also referred…
