A Covariant Distributed-Field Ansatz for Late-Time Brane-Dark-Sector Energy Exchange (The Q-Rubin Framework, Version 3.2)

We propose a covariant phenomenological ansatz for late-time energy exchange between a pressureless matter-like sector and an emergent dark sector on a four-dimensional brane. The interaction is represented by a transfer current JμJ^\mu coupled to a dimensionless emergent scalar...
