双标度SYK中的双倍希尔伯特空间

Doubled Hilbert space in double-scaled SYK

Kazumi Okuyama

AI总结:

本文在双标度SYK模型中提出用双倍希尔伯特空间表示物质关联函数,并发现弦交点计数算符需经纠缠器与解纠缠器共轭,通过两点和四点函数验证了该结构。

摘要:

我们考虑双标度SYK(DSSYK)模型中的物质关联函数。结果表明,物质关联函数可以用双倍希尔伯特空间$\mathcal{H}\otimes\mathcal{H}$来简洁表达,其中$\mathcal{H}$是$q$变形谐振子的Fock空间(也称为弦希尔伯特空间)。在这一形式体系中,我们发现计数弦交点的算符应当被某种“纠缠器”和“解纠缠器”共轭。我们明确地针对DSSYK中物质算符的两点函数和四点函数展示了这一结构。

英文摘要:

We consider matter correlators in the double-scaled SYK (DSSYK) model. It turns out that matter correlators have a simple expression in terms of the doubled Hilbert space $\mathcal{H}\otimes\mathcal{H}$, where $\mathcal{H}$ is the Fock space of $q$-deformed oscillator (also known as the chord Hilbert space). In this formalism, we find that the operator which counts the intersection of chords should be conjugated by certain ``entangler'' and ``disentangler''. We explicitly demonstrate this structure for the two- and four-point functions of matter operators in DSSYK.
