Energy momentum tensor of a non-minimally coupled scalar from the equivalence of the Einstein and Jordan frames
Sk. Moinuddin, Pradip Mukherjee, Anirban Saha +1
Unlike the minimally coupled gravity theory where matter is coupled with gravity in such a manner so that one can differentiate the matter and gravity sector uniquely, the non-mini…
A field theoretic approach to the energy momentum tensor for theories coupled with gravity
Pradip Mukherjee, Anirban Saha, Amit Singha Roy
We provide a field-theoretic algorithm of obtaining energy momentum tensor (EMT) for gravitationally coupled theories. The method is based on an auxiliary field theory and equally…
Non-minimally coupled quintessence DE model with a cubic galileon term --A Dynamical System Analysis
Somnath Bhattacharya, Pradip Mukherjee, Amit Singha Roy +1
We consider a scalar field which is generallly non-minimally coupled to gravity and has a characteristic cubic Galilean-like term in the kinetic part of the action, in presence of…
