我们在四维最大ISO(7)规范超引力的纯膨胀子扇区内研究D2-膜全息,该扇区作为IIA型超引力在S$^6$上的一致截断而获得。在对偶框架中,由无质量IIA理论约化得到的四维拉格朗日量表现出标度相似性,从而反映了对偶三维最大超对称杨-米尔斯理论的广义共形对称性。利用辅助时空构造,我们表明在质量IIA理论中已知的全息CFT$_3$固定点和RG流在无质量IIA理论中有自然的对应物:由广义RG流连接的具有广义共形对称性的QFT$_3$,我们数值构造了这些流。我们还重新审视了库仑分支解,并提出了将Gubser奇异性判据扩展到表现出标度相似性的超引力理论。
英文摘要
We study D2-brane holography within the purely dilatonic sector of four-dimensional maximal ISO(7)-gauged supergravity, obtained as a consistent truncation of type IIA supergravity on S$^6$. In the dual frame, the four-dimensional Lagrangian resulting from the reduction of the massless IIA theory exhibits scaling similarity, thus reflecting the generalised conformal symmetry of the dual three-dimensional maximally supersymmetric Yang-Mills theory. Using an auxiliary spacetime construction, we show that the holographic CFT$_3$ fixed points and RG-flows known in the massive IIA theory have natural counterparts in the massless IIA theory: QFT$_3$s with generalised conformal symmetry connected by generalised RG-flows, which we construct numerically. We also revisit the Coulomb branch solutions and propose an extension of Gubser's singularity criterion to supergravity theories exhibiting scaling similarity.
