One-Loop Effective Action for Nonminimal Natural Inflation Model
Sandeep Aashish, Sukanta Panda
Recent and upcoming experimental data as well as the possibility of rich phenomenology has spiked interest in studying the quantum gravitational effects in cosmology at low (inflat…

Quantum aspects of antisymmetric tensor field with spontaneous Lorentz violation
Sandeep Aashish, Sukanta Panda
We study the quantization of a simple model of antisymmetric tensor field with spontaneous Lorentz violation in curved spacetime. We evaluate the 1-loop corrections at first order…

Avoiding instabilities in antisymmetric tensor field driven inflation
Sandeep Aashish, Abhilash Padhy, Sukanta Panda
Models of inflation with antisymmetric tensor studied in the past are plagued with ghost instability even in an unperturbed FRW background. We show that it is possible to avoid gho…
