Teleparallel scalar-tensor gravity through cosmological dynamical systems

Understand

Scalar-tensor theories offer the prospect of explaining the cosmological evolution of the Universe through an effective description of dark energy as a quantity with a non-trivial evolution.

• In this work, we investigate this feature of scalar-tensor theories in the teleparallel gravity context.
• Teleparallel gravity is a novel description of geometric gravity as a torsional-rather than curvature-based quantity which presents a new foundational base for gravity.
• Our investigation is centered on the impact of a nontrivial input from the kinetic term of the scalar field.
