因果费米子系统与量子理论的ETH方法

Causal Fermion Systems and the ETH Approach to Quantum Theory

Felix Finster, Jürg Fröhlich, Marco Oppio, Claudio F. Paganini

摘要:

在回顾了“因果费米子系统”理论(CFS理论)和量子理论的“事件、树和历史方法”(ETH方法)之后,我们比较了这两个一般框架下的一些数学结构,并讨论了相似性和差异。对于因果费米子系统,我们引入未来代数因果费米子系统固有的因果关系的基础上。这些代数类似于先前在ETH方法中引入的代数。然后,我们表明,因果费米子系统的时空点具有类似的属性的“事件”,定义在ETH的方法。我们的讨论是基于因果费米子系统描述闵可夫斯基空间的调查结果表明,一个运营商代表一个时空点与代数在其因果未来,到微小的修正,取决于正则化长度。

英文摘要:

After reviewing the theory of "causal fermion systems" (CFS theory) and the "Events, Trees, and Histories Approach" to quantum theory (ETH approach), we compare some of the mathematical structures underlying these two general frameworks and discuss similarities and differences. For causal fermion systems, we introduce future algebras based on causal relations inherent to a causal fermion system. These algebras are analogous to the algebras previously introduced in the ETH approach. We then show that the spacetime points of a causal fermion system have properties similar to those of "events", as defined in the ETH approach. Our discussion is underpinned by a survey of results on causal fermion systems describing Minkowski space that show that an operator representing a spacetime point commutes with the algebra in its causal future, up to tiny corrections that depend on a regularization length.
