Note on stability and microcausality in Lorentz violating antisymmetric tensor field
Sandeep Aashish
The fundamental issues of microcausality and energy positivity conditions are important to be investigated in the context of spontaneous Lorentz violating theories. We check the mi…
Covariant Quantum Gravitational Corrections to Scalar and Tensor Field Models
Sandeep Aashish
Recent and upcoming experimental data as well as the possibility of rich phenomenology have spiked interest in studying the quantum effects in cosmology at low (inflation-era) ener…
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…
