Gravitational background of Alice vortices and R7-branes
Abstract
Codimension-two vortex solutions are important solitonic objects in both quantum field theory and gravity. In this paper, we construct a class of codimension-two Alice-vortex solutions in axio-dilaton gravity, in which monodromy around the vortex enacts the axion transformation C 0 ↦ − C 0 . In IIB supergravity, this furnishes a class of R7-brane backgrounds of the sort predicted by the swampland cobordism conjecture. Such configurations generically carry an intrinsic dipole moment. We extract additional properties of such branes from scattering probes. These results provide further evidence that the world-volume theory of an R7-brane is an eight-dimensional nonsupersymmetric interacting quantum field theory.
