Relational Time as a Stochastic Variable in ADM Gravity
Pradosh Keshav MV
The problem of time in canonical quantum gravity remains one of the most significant challenges, primarily due to the "frozen" formalism emerging from the Wheeler-DeWitt equation.…

Spontaneous Symmetry Breaking as a Late-Time Trigger for Interacting Dark Energy
Pradosh Keshav MV, NS Kavya, Kenath Arun
Persistent tensions in the Hubble constant (H0) and the matter clustering parameter (S8) motivate late-time new physics that suppresses structure growth without significantly alter…

Quintessence and false vacuum: Two sides of the same coin?
Pradosh Keshav M. V., Arun Kenath
We study late-time acceleration scenarios using a quintessence field initially trapped in a metastable false vacuum state. The false vacuum has non-zero vacuum energy and could dri…
