量子场论中的局部性公理与$C^*$ -代数的张量积

The Locality Axiom in Quantum Field Theory and Tensor Products of $C^*$-algebras

Romeo Brunetti, Klaus Fredenhagen, Paniz Imani, Katarzyna Rejzner

摘要:

相互独立系统的原型是局限于类空分离区域的系统。在局部协变量子场论的框架中,我们证明了类空分离区域中可观测量的可交换性可以编码在函子的张量结构中,该函子将单位$C^*$ -代数(局部可观测代数)与全局双曲时空关联起来。这在局部代数满足分裂性质并涉及$C^*$ -代数的极小张量积的假设下成立。

英文摘要:

The prototype of mutually independent systems are systems which are localized in spacelike separated regions. In the framework of locally covariant quantum field theory we show that the commutativity of observables in spacelike separated regions can be encoded in the tensorial structure of the functor which associates unital $C^*$-algebras (the local observable algebras) to globally hyperbolic spacetimes. This holds under the assumption that the local algebras satisfy the split property and involves the minimal tensor product of $C^*$-algebras.
