Motivated by Palle’s investigation on the handness of chirality of vorticity in Einstein–Cartan cosmology [Entropy 5 (2014)], several aspects of chiral torsional handness in magnetogenesis and cosmology are presented. In the first one, we obtain torsion bounds from massive photons and axial anomalies. In the second, we deal with magnetogenesis from photon mass and in the third, we discuss chiral torsion degrees of freedom to obtain a torsion cosmological constant dependent solution. The torsion solution decays fast and implies a strong suppression of torsion at present universe. Our result contains the Poplawski [Phys. Lett. B (2010)] results in the case axial torsion vector associated to Einstein–Cartan fermionic sector matter and conformal anomalies of quarks. In the third example, a magnetic field bound from chiral torsionic dynamos is obtained as 1011G. In the non-minimal cosmological models, chiral dynamos are sourced by massive photons, London currents and chiral magnetic effect (CME). Chiral chemical potential is found to be mimic by torsion. Cosmological constant bound Λ 1034cm2 is found. At the early universe, the cosmological constant Λ 1022cm2 is obtained. Torsion used in the present universe is 1019GeV. In the last and fourth example, chiral anisotropic currents are obtained and magnetic helicity is shown to depend upon torsion when the chiral chemical potential is non-constant.

来自手性费米子扭转的宇宙学常数、轴向异常和光子质量发电机

受帕勒对爱因斯坦-嘉当宇宙学中涡度手性手性的研究的启发[ 5(2014)],介绍了磁发生和宇宙学中手性扭转手性的几个方面。在第一个中,我们从大质量光子和轴向异常中获得扭转界限。在第二部分中,我们处理来自光子质量的磁发生,在第三部分中,我们讨论手性扭转自由度以获得扭转宇宙学常数相关的解。扭转解的衰减速度很快,意味着目前宇宙中的扭转受到了强烈的抑制。我们的结果包含 Poplawski [物理。莱特。乙(2010)] 得出与 Einstein-Cartan 费米子扇形物质和夸克共形异常相关的情况轴向扭转矢量。在第三个例子中,从手性扭转发电机绑定的磁场获得为10-11G. 在非最小宇宙学模型中,手性发电机来源于大量光子、伦敦电流和手性磁效应 (CME)。发现手性化学势可以通过扭转来模拟。宇宙常数界Λ 10-34厘米-2被发现。在早期宇宙中,宇宙学常数Λ 1022厘米-2获得。目前宇宙中使用的扭转是10-19锗钒. 在最后一个和第四个示例中,获得了手性各向异性电流,并且当手性化学势不恒定时,磁螺旋度显示为取决于扭转。
