We construct smooth nonsupersymmetric soliton solutions with D1-brane, D5-brane, and momentum charges in type IIB supergravity compactified on T 4 S 1 , with the charges along the compact directions. This generalizes previous studies of smooth supersymmetric solutions. The solutions are obtained by considering a known family of U1 U1 invariant metrics, and studying the conditions imposed by requiring smoothness. We discuss the relation of our solutions to states in the CFT describing the D1-D5 system and describe various interesting features of the geometry.

Non-BPS multi-bubble microstate geometries

“…The smoothness conditions at the bolt (r = c) are generalizations of those discussed in [45] and in JMaRT [34]. At the bolt, the functions W , H I behave as…”

“…To date there exists only a handful of exact microstate solutions that have the mass and charges of nonextremal black holes. The earliest-known examples are the solutions of Jejjala, Madden, Ross and Titchener (JMaRT) [34] and their generalizations [35][36][37]. The JMaRT solutions have more angular momentum than a physical black hole with the same mass and charges, and hence in the decoupling limit correspond to CFT states that are far away from the sector which dominates the black hole ensemble.…”

“…For constant H this bolt is the unique cycle of the solution and, as was shown in [45], the solution reduces to the JMaRT solution [34].…”

“…These solutions are generalizations of the JMaRT solutions [34], and reduce to them upon removing the additional Gibbons-Hawking center.…”

An inverse scattering formalism for STU supergravity

“…This requires changing the asymptotic behavior of M(w) for w → ∞. Together with the results of the present paper, this will allow us to construct the 5d charged rotating Cvetič-Youm [24] metric which in turn will lead to an inverse scattering construction of the JMaRT fuzzball [25]. Such a construction is highly desirable as it will naturally lead to ways to generalize the JMaRT fuzzball.…”
