Query: Energy momentum tensor of a non-minimally coupled scalar from the
  equivalence of the Einstein and Jordan frames   Owing to it's non-minimal nature of coupling with gravity, the scalar field
in a scalar-tensor theory is covariantly conserved with more than one choice of
its energy-momentum tensor (EMT). Apparently this ambiguity in the choice of
the symmetric EMT results from the way the conserved EMT is identified by
different algebraic manipulations of the gravity field equation in such
non-minimally coupled (NMC) theories. In this paper, we demonstrate that %using
, one can arrive at these different choices of EMT, not by mere algebraic
manipulation, but by demanding the equivalence of a NMC theory in Jordan frame
with a minimally coupled theory in Einstein frame at the level of physical
laws.
