Gravitational waves from inflation with antisymmetric tensor field
Sandeep Aashish, Abhilash Padhy, Sukanta Panda
We build upon the past studies of inflation with rank-2 antisymmetric tensor field, including here the tensor perturbations to metric. We perform a comprehensive analysis of the ba…

Covariant quantum corrections to a scalar field model inspired by nonminimal natural inflation
Sandeep Aashish, Sukanta Panda
We calculate the covariant one-loop quantum gravitational effective action for a scalar field model inspired by the recently proposed nonminimal natural inflation model. Our calcul…
