自旋统计联系是否有动力学原因?
Is there a dynamical cause of the spin-statistics connection?
摘要:
自旋统计联系(SSC)的现有证据是运动学的。C S Unnikrishnan提出,导致SSC的动力学相互作用将涉及自旋和perforce引力,这是唯一已知的普遍力。对于两个相同粒子的散射,他考虑了它们的自旋与它们通过宇宙物质能量散射运动产生的引力磁场的相互作用。在那里,直接和粒子交换的散射振幅积累了不同的量子相位,这些量子相位提供了它们之间的相关玻色子/费米子符号,而不应用特设SSC规则。这里它表明,在量子力学中的SSC的标准实施所给出的散射概率实际上不是从上述相互作用的散射粒子的大多数初始自旋状态。相反,需要一种未实现的特殊动力学相互作用。此外,如上所述的自旋-重力-磁相互作用(具有警告)将导致对原子能级的大的不可测量的自旋-轨道耦合类型效应。还提供了与典型的基于旋转的证明的比较。
英文摘要:
Extant proofs of the spin-statistics connection (SSC) are kinematical. C S Unnikrishnan has suggested that a dynamical interaction leading to the SSC would involve spin and perforce gravity, the only known universal force. For the scattering of two identical particles, he considers [arXiv: gr-qc/0406043] the interaction of their spins with the gravito-magnetic field generated by their scattering motion through cosmic matter-energy. There the direct and particles-exchanged scattering amplitudes accumulate different quantum phases which provide the relevant bosonic/fermionic sign between them without applying the ad hoc SSC rule. Here it is shown that the scattering probabilities given by the standard implementation of SSC in quantum mechanics are actually not obtained from the above interaction for most initial spin states of the scattering particles. Instead, an unrealized peculiar dynamical interaction is required. Further, a spin-gravito-magnetic interaction as above (with caveats) would result in a large unmeasured spin-orbit coupling type effect on atomic energy levels. A comparison with a typical rotation based proof is also provided.
