一般协变框架下弯曲时空流形上量子场的自旋统计定理

A spin-statistics theorem for quantum fields on curved spacetime manifolds in a generally covariant framework

Rainer Verch

摘要:

一个模型无关的,局部一般协变的量子场论制定超过四维,全球双曲时空将得到推广类似的,以前的方法。在这里,一般的协变量子场论是将量子场分配给具有自旋结构的全局双曲时空,其中每个量子场在它被分配的时空上传播。我们假设一些非常自然的条件,如局部广义协方差、因果动力学定律的存在、理论中所有量子场的旋量或张量类型都是固定的,以及闵可夫斯基时空中的量子场满足通常的条件,我们将证明自旋统计定理成立:如果对于某些时空,相应的量子场服从自旋和统计之间的“错误”联系,那么在每个时空上,是微不足道的。

英文摘要:

A model-independent, locally generally covariant formulation of quantum field theory over four-dimensional, globally hyperbolic spacetimes will be given which generalizes similar, previous approaches. Here, a generally covariant quantum field theory is an assignment of quantum fields to globally hyperbolic spacetimes with spin-structure where each quantum field propagates on the spacetime to which it is assigned. Imposing very natural conditions such as local general covariance, existence of a causal dynamical law, fixed spinor- or tensor-type for all quantum fields of the theory, and that the quantum field on Minkowski spacetime satisfies the usual conditions, it will be shown that a spin-statistics theorem hols: If for some spacetimes the corresponding quantum field obeys the "wrong" connection between spin and statistics, then all quantum fields of the theory, on each spacetime, are trivial.
