M. Davidse, M. de Vroome, U. Theis, S. Vandoren

TL;DR
This paper explores various instanton solutions in the universal hypermultiplet, including multi-centered and mixed fivebrane-membrane instantons, using a double-tensor multiplet framework to describe these configurations.
Contribution
It introduces new instanton solutions in the universal hypermultiplet, expanding previous analyses with multi-centered and mixed instantons in a double-tensor multiplet setting.
Findings
Derived near-extremal multi-centered instanton solutions.
Described mixed fivebrane-membrane instantons.
Extended the understanding of instanton configurations in hypermultiplets.
Abstract
We expand our previous analysis on fivebrane and membrane instanton solutions in the universal hypermultiplet, including near-extremal multi-centered solutions and mixed fivebrane-membrane charged instantons. The results are most conveniently described in terms of a double-tensor multiplet.
