Bound states of KK monopole and momentum
Abstract
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.
