论文摘要
我们考虑了E $ _9 $的普通Scherk-Schwarz降低到d = 2个时空维度，尤其是构建所有可以以这种方式获得的所有测量超级超级超级超级超级超级的标量电势。这为多种理论提供了一个有趣的真空结构，涵盖了许多新广告$ _2 $案例。作为一个应用程序，我们证明了$ s^8 \ times s^1 $在so（9）测量最大超级重力上的十一维超级截断的一致性。其超对称的SO（9） - 激动真空的波动从相互作用的D0抗体的动力学上描述。
We consider generalized Scherk-Schwarz reductions of E$_9$ exceptional field theory to D=2 space-time dimensions and in particular construct the resulting scalar potential of all gauged supergravities that can be obtained in this way. This provides the first general expression for a multitude of theories with an interesting structure of vacua, covering potentially many new AdS$_2$ cases. As an application, we prove the consistency of the truncation of eleven-dimensional supergravity on $S^8\times S^1$ to SO(9) gauged maximal supergravity. Fluctuations around its supersymmetric SO(9)-invariant vacuum describe holographically the dynamics of interacting D0-branes.
