Abstract

We show that a scalar field without a kinetic term in the Lagrangian density, coupled to a covariant divergence of the torsion vector in the Einstein-Cartan theory of gravity, becomes kinetic in its general-relativistic equivalent formulation. Dynamical scalar fields may therefore be emergent.
