| contents | In this study we explore the cosmological behavior of a non-minimally coupled scalar field that is linked to torsion gravity. We demonstrate the Sorkin-Schutz formalism with general power law teleparallel torsion coupling. The autonomous dynamical system has been formulated. The phase space diagrams have been analysed at each critical point. The critical points representing different eras of Universe evolution starting from radiation, dark matter (DM), and dark energy (DE) have been investigated. The scaling attractors with the viable range of model parameters have been obtained using exponential scalar field couplings. This modified version of the formalism describes some novel scaling solutions. |
