Stability of Wilson Loops and Other Observables in Various Type IIB Backgrounds

Dimitrios Chatzis

AI总结:

本研究针对IIB型超引力的十维D5膜背景,分析Wilson圈等可观测量的线性涨落稳定性,通过本征值问题与数值分析,验证了基于探测弦能量凹性的稳定性结论。

摘要:

本工作针对近期文献中出现的IIB型超引力若干十维解,研究各类可观测量(Wilson圈、't Hooft圈和纠缠熵)在坐标线性涨落下的稳定性。这些背景由相交且缠绕的D5膜定义,其全息对偶场论被推测具有禁闭性,且拥有由Little String Theory(小弦理论)主导的非局域紫外完备性。本研究通过分析每种情形的本征值问题并提供数值分析,验证了此前利用探测弦能量凹性条件对这类解稳定性提出的论断。

英文摘要:

This work involves the stability study of various observables (Wilson loop, 't Hooft loop and Entanglement Entropy) under linear fluctuations of the coordinates for certain ten-dimensional solutions of type IIB Supergravity that have appeared in the literature recently. These backgrounds are defined using intersecting and wrapped D5 branes, their holographically dual field theories are speculated to confine and they have a non-local UV completion that is governed by Little String Theory. The present study confirms previous claims on the stability of the solutions made using the concavity condition for the energy of the probe strings, by studying the eigenvalue problem for each case and also providing a numerical analysis.
