CAR-代数的扭曲对偶

Twisted duality of the CAR-Algebra

Hellmut Baumgärtel, Matthias Jurke, Fernando Lledó

摘要:

本文给出了(自对偶)CAR-代数在任意Fock表示下的扭对偶性质M(q)′ = Z M(q^ \perp)Z* 的一个完整证明.证明是基于自然的Halmos分解的(参考)希尔伯特空间时,两个合适的封闭子空间已被区分。我们使用模块化的理论和技术开发的加藤关于对投影在一些必要的步骤的证明。作为副产品的证明,我们得到一个明确的和简单的公式的图的模运算符。这个公式也可以应用于费米子自由网,从而给出了任意双锥的模算符公式。

英文摘要:

We give a complete proof of the twisted duality property M(q)'= Z M(q^\perp) Z* of the (self-dual) CAR-Algebra in any Fock representation. The proof is based on the natural Halmos decomposition of the (reference) Hilbert space when two suitable closed subspaces have been distinguished. We use modular theory and techniques developed by Kato concerning pairs of projections in some essential steps of the proof. As a byproduct of the proof we obtain an explicit and simple formula for the graph of the modular operator. This formula can be also applied to fermionic free nets, hence giving a formula of the modular operator for any double cone.
