Summary:General relativity characterizes gravity as a geometric property exhibited on spacetime by massive objects, while teleparallel gravity achieves the same results at the level of equations, by taking a torsional perspective of gravity. Similar to the f ( R ) theory teleparallel gravity can also be generalized to f ( T ), with the resulting field equations being inherently distinct from f ( R ) gravity in that they are second order, while in the former case they turn out to be fourth order. In the present case, a minimally coupled scalar field is investigated in the f ( T ) gravity context for several forms of the scalar field potential. A number of new f ( T ) solutions are found for these potentials. Their respective state parameters are also being examined.
