An Einstein-Cartan ekpyrotic model with a steep-to-plateau scalar potential supports a torsion-driven nonsingular bounce in homogeneous contraction without chaotic behavior in the explored parameter space.
Here x ≃ 0, y ≃ 0, z ≃ 1, corresponding to the usual radiation and matter dominated eras [ 25]
