双重重叠与有限耦合 't Hooft 圈

Dual overlaps and finite coupling 't Hooft loops

Tamas Gombor, Zoltán Bajnok

AI总结:

本文通过对偶化一种嵌入的渐近重叠公式描述另一种嵌入,并应用于计算 N=4 SYM 中存在 't Hooft 线时局部算子的渐近期望值,揭示了特定分次下重叠不可因子化的奇特特征。

摘要:

可积 $su(2\vert2)_{c}$ 对称模型具有 $osp(2\vert2)$ 对称性的可积边界,后者可以通过两种不同方式嵌入到 $su(2\vert2)_{c}$ 中。我们将先前获得的一种嵌入的渐近重叠公式对偶化,以描述另一种嵌入,并将结果应用于描述在 N=4 SYM 中存在 't Hooft 线时局部算子的渐近期望值。该设定的一个奇特特征是,在某些分次下,仅有后裔态与边界态的重叠非零,且重叠公式对于 Bethe 根不可因子化。

英文摘要:

Integrable $su(2\vert2)_{c}$ symmetric models have integrable boundaries with $osp(2\vert2)$ symmetries, which can be embedded into $su(2\vert2)_{c}$ in two different ways. We dualize the previously obtained asymptotic overlap formulas for one of the embeddings to describe the other embedding and apply the results to describe the asymptotic expectation values of local operators in the presence of a 't Hooft line in N=4 SYM. A peculiar feature of the setting is that in certain gradings only descendant states have non-vanishing overlaps with the boundary state and the overlap formula is not factorized for the Bethe roots.
