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.

费米反弹曲率宇宙学中的量子电热机制

在费米反弹曲率机制的背景下，我们分析了由爱因斯坦-嘉当-霍尔斯特-夏马-基布尔理论中的非动态扭转场产生的四个费米子相互作用的单环辐射校正。我们表明，单环辐射校正产生的贡献修改了能量动量张量，{\it 模仿}了一种有效的 Ekpyrotic 流体贡献。由于这些原因，我们称这种效应为 {\it 量子 Ekpyrotic} 机制。这导致对能量-动量张量的各向异性贡献的动态冲洗，而不引入任何新的额外 Ekpyrotic 流体。我们讨论了弹跳机制的稳定性，并推导出维耦合常数 $\xi$ 的重整化群流，检查其符号的任何变化是否朝着弹跳发生。
