外尔的相对论势:引力存在下量子物理的一个途径?

Relativistic potential of Weyl: a gateway to quantum physics in the presence of gravitation?

Ram Gopal Vishwakarma

摘要:

引力和电动力学之间的著名对应强调了Lanczos张量的重要性--外尔张量的势--这是在四维伪黎曼时空中制定的任何引力度量理论的固有结构元素。然而,这个巧妙的发现在很大程度上被忽视了。我们通过在某些特定的时空中导出它的表达式来阐明这个重要的量,并试图找出它实际上代表什么。我们发现,Lanczos势张量并不代表引力场的势,这已被各种证据所证实。相反,它富含各种量子特征的签名,这为引力的几何体现的核心提供了新的见解。

英文摘要:

The well-noted correspondence between gravitation and electrodynamics emphasizes the importance of the Lanczos tensor -- the potential of the Weyl tensor -- which is an inherent structural element of any metric theory of gravity formulated in a 4-dimensional pseudo Riemannian spacetime. However, this ingenious discovery has gone largely unnoticed. We elucidate this important quantity by deriving its expressions in some particularly chosen spacetimes and try to find out what it represents actually. We find out that the Lanczos potential tensor does not represent the potential of the gravitational field, as is ascertained by various evidences. Rather, it is enriched with various signatures of quantum character, which provides a novel insight into the heart of a geometric embodiment of gravity.
