Non-Gaussianity Consistency Relations, Initial States and Back-reaction
Sandipan Kundu
We explore the consistency relations for the three-point functions, in the squeezed limit, of scalar and tensor perturbations in single-field inflation with general initial conditi…

Inflation with General Initial Conditions for Scalar Perturbations
Sandipan Kundu
We explore the possibility of a single field quasi-de Sitter inflationary model with general initial state for primordial fluctuations. In this paper, first we compute the power sp…

Constraining the Inflationary Equation of State
Lotty Ackerman, Willy Fischler, Sandipan Kundu +1
We explore possible constraints on the inflationary equation state: p=wρ. While w must be close to -1 for those modes that contribute to the observed power spectrum, for those mode…
