标题： Connecting flux vacua through scalar field excursions

摘要： 我们展示如何将在通量量子上不同的通量真空视为一个扩展场空间中单一标量势能的不同真空，这解决了通过薄域壁的分离问题。 这一观察结果受到AdS距离猜想的启发，使得可以使用通常的场空间度量来计算不同真空之间的距离。 我们验证了具体的例子，如尺度分离的IIA通量真空和IIB Freund-Rubin真空，发现距离猜想（对于标量场）得到满足，并且扩展场空间中的渐近方向确实是双曲的。 这个扩展的场空间包含II型弦理论中不稳定的$\tilde{\mathrm{D}}p$-膜上的快子场，这些场可以诱导稳定D-膜的膜电荷。 我们建议，要求连续插值可以精炼边界猜想，并预言不稳定$\tilde{\mathrm{D}}p$-膜的存在。 显示英文摘要

摘要： We show how flux vacua that differ from each other in flux quanta can be seen as different vacua in a single scalar potential of an enlarged field space, which resolves the separation by thin domain walls. This observation, which is motivated by the AdS Distance Conjecture, allows one to compute distances between different vacua using the usual field space metric. We verify for explicit examples such as scale-seperated IIA flux vacua and the IIB Freund-Rubin vacua that the Distance Conjecture (for scalar fields) is satisfied and that the asymptotic directions in the enlarged field space are indeed hyperbolic. This enlarged field space contains the tachyon fields on the unstable $\tilde{\mathrm{D}}p$-branes of type II string theory, which can induce the brane charges of the stable D-branes. We suggest that requiring continuous interpolations refines the Cobordism Conjecture and postdicts the existence of unstable $\tilde{\mathrm{D}}p$-branes.
