Minimal coupling in presence of non-metricity and torsion
Abstract We deal with the question of what it means to define a minimal coupling prescription in presence of torsion and/or non-metricity, carefully explaining while the naive substitution $$\partial \rightarrow \nabla $$ ∂→∇ introduces extra couplings between the matter fields and the connection th...
