Bound states of KK monopole and momentum

الأصل · EN

We construct metrics for multiple Kaluza-Klein monopole-branes carrying travelling waves along one of the isometry directions (not KK monopole fibre) in ten dimensional type IIB supergravity and relate them via string dualities to two charge Mathur-Lunin metrics. We find that adding momentum to Nₖ coincident monopoles leads them to separate in the transverse direction into Nₖ single monopoles. Hence the bound state metrics are perfectly smooth, without Zₙₖ singularities, and correspond to a system with non-zero extension in the transverse directions. We compare this solution with other solutions with KK monopole.
