Phantom dark energy from scalar$-$torsion coupling

General Relativity and Quantum Cosmology 2021-01-26 v2

Abstract

We show that a scalar field without a kinetic term in the Lagrangian density, coupled to the covariant divergence of the torsion vector in the Einstein-Cartan theory of gravity, becomes kinetic in its general-relativistic equivalent formulation. The resulting kinetic term is negative: such a scalar field could be a source of phantom dark energy.
