Hyojoong Kim, Sunchang Kim, Nakwoo Kim, Jung Hun Lee

摘要:

七维非齐次Sasaki-Einstein流形$Y^{p,k}(KE_4)$给出了AdS/CFT对应的一个具有挑战性的例子。目前,他们的$KE_4=\mathbb{CP}^2$基场论模型仅在限定的$3p/2\le k \le 2p$范围内提出,如具有$SU(N)\times SU(N)\times SU(N)$规范群的${\cal N}=2$-Chern-Simons-物质理论,9个双基本手征多重态通过立方超势相互作用。为了进一步阐明这种对应关系,我们在经典和量子水平上使用粒子近似。利用测地运动建立了守恒量的AdS/CFT映射,并在$Y^{p,k}$中求解了标量Laplace方程。本征模也为${\rm AdS}_4\times Y^{p,k}$中的$D=11$超引力提供了一个有趣的Kaluza-Klein谱子集,并且与对偶共形场论中用物质多重态表示的保护算符是对偶的.

英文摘要:

Seven-dimensional inhomogeneous Sasaki-Einstein manifolds $Y^{p,k}(KE_4)$ present a challenging example of AdS/CFT correspondence. At present, their field theory duals for $KE_4=\mathbb{CP}^2$ base are proposed only within a restricted range $3p/2\le k \le 2p$ as ${\cal N}=2$ quiver Chern-Simons-matter theories with $SU(N)\times SU(N)\times SU(N)$ gauge group, nine bifundamental chiral multiplets interacting through a cubic superpotential. To further elucidate this correspondence, we use particle approximation both at classical and quantum level. We setup a concrete AdS/CFT mapping of conserved quantities using geodesic motions, and turn to solutions of scalar Laplace equation in $Y^{p,k}$. The eigenmodes also provide an interesting subset of Kaluza-Klein spectrum for $D=11$ supergravity in ${\rm AdS}_4\times Y^{p,k}$, and are dual to protected operators written in terms of matter multiplets in the dual conformal field theory.
