可积量子场论中的束缚态算符和楔定域性

Bound state operators and wedge-locality in integrable quantum field theories

Yoh Tanimoto

摘要:

考虑了具有在物理带中具有极点的分解S-矩阵的标量二维量子场论。在我们以前的工作中,我们引入了束缚态算符,并构造了楔形观测量的候选算符。在对S-矩阵的一些附加假设下,我们证明了,为了得到它们的强交换性,只要证明左右束缚态算符之和的本质自伴性就足够了.这种基本的自伴性一直表现到二粒子分量。

英文摘要:

We consider scalar two-dimensional quantum field theories with the factorizing S-matrix which has poles in the physical strip. In our previous work, we introduced the bound state operators and constructed candidate operators for observables in wedges. Under some additional assumptions on the S-matrix, we show that, in order to obtain their strong commutativity, it is enough to prove the essential self-adjointness of the sum of the left and right bound state operators. This essential self-adjointness is shown up to the two-particle component.
