Anisotropic Inflation in Dipolar Bose-Einstein Condensates
Arun Rana, Abhijit Pendse, Sebastian Wüster +1
Early during the era of cosmic inflation, rotational invariance may have been broken, only later emerging as a feature of low-energy physics. This motivates ongoing searches for re…
Coupled Quintessence scalar field model in light of observational datasets
Trupti Patil, Ruchika, Sukanta Panda
We do a detailed analysis of a well-theoretically motivated interacting dark energy scalar field model with a time-varying interaction term. Using current cosmological datasets fro…
Two-loop Vilkovisky-DeWitt effective action for scalar field minimally coupled with gravity
Ketankumar Jadav, Sukanta Panda, Abbas Altafhussain Tinwala
It is known that Vilkovisky-DeWitt's effective action is gauge invariant off-shell and independent of quantum field parametrization. In this work, we perform the calculation of the…
Ghost Free Theory in Unitary Gauge: A New Candidate
Pawan Joshi, Sukanta Panda, Archit Vidyarthi
We propose an algebraic analysis using a 3+1 decomposition to identify conditions for a clever cancellation of the higher derivatives, which plagued the theory with Ostrogradsky gh…
Inflation using a triplet of Antisymmetric tensor fields
Abhijith Ajith, Sukanta Panda
We study an inflation model driven by a triplet of antisymmetric tensor fields, with minimal and nonminimal couplings to gravity. First, we show that the presence of a triplet of a…
Constant-Roll Inflation in modified gravity model using Palatini Formalism
Sukanta Panda, Arun Rana, Rahul Thakur
In this work, we study a constant-roll inflationary model in the Palatini formalism using modified gravity. Here our action consists a non-minimal coupling of a scalar field wi…
