Revisiting Lagrangian Formulation of Stochastic inflation
Rajat Kumar Panda, Sukanta Panda, Abbas Tinwala
We revisit the Lagrangian formulation of stochastic inflation, where the path-integral approach is employed to derive the Langevin equation governing the dynamics of long-wavelengt…

One-particle irreducibility of Vilkovisky-DeWitt effective action
Sukanta Panda, Abbas Tinwala, Ketankumar Jadav
The effective action formalism introduced by Vilkovisky and later modified by DeWitt is completely covariant suitable for obtaining an effective action that is independent of the p…

Open EFT treatment of Inflation with Thermal Initial Conditions
Abbas Tinwala, Ashish Narang, Subhendra Mohanty +1
Investigating the thermal inflationary model, we introduce stochastic effects, incorporating a cutoff parameter which distinguishes between quantum and classical modes. Testin…
