复杂经典场:反射积极性的一个框架

Complex Classical Fields: A Framework for Reflection Positivity

Arthur Jaffe, Christian D. Jäkel, Roberto E. Martinez

摘要:

我们探讨了一个复杂的经典领域的框架,适合于描述量子场论。我们的场是希尔伯特空间上的线性变换,因此它们比概率测度的随机变量更一般。我们的方法推广了Osterwalder和Schrader的欧几里得域的构造。在描述中性粒子的量子场论中,我们允许复值经典场。从分析的角度来看,使用我们的方法的关键是反射积极性。我们调查的领域的傅立叶表示的条件,以确保反射积极性举行。我们还展示了反射正性是如何通过欧氏空间的各种时空紧化来保持的。

英文摘要:

We explore a framework for complex classical fields, appropriate for describing quantum field theories. Our fields are linear transformations on a Hilbert space, so they are more general than random variables for a probability measure. Our method generalizes Osterwalder and Schrader's construction of Euclidean fields. We allow complex-valued classical fields in the case of quantum field theories that describe neutral particles. From an analytic point-of-view, the key to using our method is reflection positivity. We investigate conditions on the Fourier representation of the fields to ensure that reflection positivity holds. We also show how reflection positivity is preserved by various space-time compactifications of Euclidean space.
