解决全息缺陷

Solving holographic defects

Georgios Linardopoulos

摘要:

最近,缺陷共形场论(dCFTs)引起了越来越多的关注,主要是因为它们使我们能够弥合我们世界的理想的,高度对称的模型(如粒子/弦对偶)和现实世界系统之间的差距。这次演讲是关于AdS/缺陷CFT对应,一个令人兴奋的新建议,加入了全息,可积性,超对称本地化和共形引导程序的力量在一个框架,这是适合于在现实世界中的缺陷系统的研究。在介绍了dCFTs和它们的一些全息实现之后,我们将给出可积dCFTs的单点函数的一些最新结果,这些单点函数是相交膜的D3-probe-D5和D3-probe-D 7系统的全息图。

英文摘要:

Defect conformal field theories (dCFTs) have been attracting increased attention recently, mainly because they enable us to bridge the gap between idealistic, highly symmetric models of our world (such as the particle/string duality) and real-world systems. This talk is about the AdS/defect CFT correspondence, an exciting new proposal that joins the forces of holography, integrability, supersymmetric localization and the conformal bootstrap program in a framework that is appropriate for the study of defects in real-world systems. After introducing dCFTs and some of their holographic realizations, we will present some recent results for the one-point functions of the integrable dCFTs that are the holographic duals of the D3-probe-D5 and the D3-probe-D7 systems of intersecting branes.
