论文摘要
非肌对称弦模型困扰着动态场的t t，这标志着真空产生的无效力。我们认为，在某些情况下，无效的动态t骨可能会因违反沼泽限制而导致与量子重力的不一致。我们描述了超对称环形$ {\ textbf {z}} _ 2 \ times {\ textbf {z}} _ 2 $ orientifold d7-branes的textbf {z}} _ 2 \ times {\ textbf {z}} _ 2 $ orientifold，在其中，动态的tadpole产生了D7-Branes的弱层，由D7-Branes置于最小范围的范围，以侵犯最小的潜在客户，以侵犯该量的量。在这些示例中，动态t的取消为构型和动力学性质提供了一致性条件（与拓扑t的拓扑条件相反，例如紧凑型空间中的RR t t取消）。我们表明，这种方法对ADS真空的Z-最终化标准进行了重新衍生，从而在4D $ \ MATHCAL {N} = 1 $ toric Quiver scfts中给出了A-Maximization的重力双重化。
Non-supersymmetric string models are plagued with tadpoles for dynamical fields, which signal uncanceled forces sourced by the vacuum. We argue that in certain cases, uncanceled dynamical tadpoles can lead to inconsistencies with quantum gravity, via violation of swampland constraints. We describe an explicit realization in a supersymmetric toroidal ${\textbf{Z}}_2\times{\textbf{Z}}_2$ orientifold with D7-branes, where the dynamical tadpole generated by displacement of the D7-branes off its minimum leads to violation of the axion Weak Gravity Conjecture. In these examples, cancellation of dynamical tadpoles provides consistency conditions for the configuration, of dynamical nature (as opposed to the topological conditions of topological tadpoles, such as RR tadpole cancellation in compact spaces). We show that this approach provides a re-derivation of the Z-minimization criterion for AdS vacua giving the gravitational dual of a-maximization in 4d $\mathcal{N}=1$ toric quiver SCFTs.
