  Within the context of the Fermi-bounce curvaton mechanism, we analyze the
one-loop radiative corrections to the four fermion interaction, generated by
the non-dynamical torsion field in the Einstein-Cartan-Holst-Sciama-Kibble
theory. We show that contributions that arise from the one-loop radiative
corrections modify the energy-momentum tensor, {\it mimicking} an effective
Ekpyrotic fluid contribution. For these reasons, we call this effect {\it
quantum Ekpyrotic} mechanism. This leads to the dynamical washing out of
anisotropic contributions to the energy-momentum tensor, without introducing
any new extra Ekpyrotic fluid. We discuss the stability of the bouncing
mechanism and derive the renormalization group flow of the dimensional coupling
constant $\xi$, checking that any change of its sign takes place towards the
bounce. This enforces the theoretical motivations in favor of the torsion
curvaton bounce cosmology as an alternative candidate to the inflation
paradigm.
