“…These branes back-react to create a geometry, AdS 3 ×S 3 ×M 4 , where M 4 is either K3 or T 4 . Superstrata are then the smooth geometries that result from back-reacting coherent combinations of particular left-moving momentum excitations in the CFT [1][2][3][4][5][6][7][8]. The holographic dictionary for these excitations and the dual geometries has been thoroughly examined and has passed numerous, precise, non-trivial tests [1,2,5,[9][10][11][12][13][14][15][16].…”

We find a two-parameter family of generalized superstrata that emerge as smooth, supersymmetric solutions in three-dimensional gauged supergravity coupled to additional scalar fields. This new family of generalized superstrata are smooth microstate geometries and may be thought of as supersymmetric Coulomb-branch extensions of the original superstrata in which the underlying supertube undergoes an elliptical deformation. These solutions had already been obtained numerically, and as series solutions, to the equations of motion, and some of them were conjectured to be supersymmetric. Here we prove the supersymmetry of an entire two-parameter family and we obtain a highly non-trivial analytic and smooth solution for a one-parameter limit in which the global symmetry of the metric is enhanced to SO(3). We also confirm that the other known families of microstrata are not supersymmetric. We conclude with a cursory analysis of some of the singular brane distributions that can be accessed from three-dimensional gauged supergravity while preserving the same supersymmetries as the superstratum, and therefore of the three-charge black hole.

“…But those states are not typical in the sense that their dual geometries are locally isometric to AdS 3 × S 3 so they do not contribute to the entropy of black holes. In the 1/8-BPS sector, the microstate geometries of typical states were firstly constructed in [19] and more solutions were found in [20,21,22,23,24] 1 . These microstate geometries which are called the superstrata in the D1-D5-P frame are asymptotic to AdS 3 × S 3 but have very complicated geometries near the horizon regions.…”

Holographic correlators on integrable superstrata

In this work, we study the 1 8 -BPS heavy-heavy-light-light correlators in the D1D5 CFT and its holographic dual. On the field theory side, we compute the fermionic four-point correlators at the free orbifold point. On the dual gravity side, we compute the correlators of the scalar operators in the supergravity limit of the D1D5 CFT. Following the strategy of [5], the four-point function is converted into a two-point function in non-trivial geometries known as superstrata which are supergravity solutions preserving 1/8 supersymmetries. We focus on a family of integrable superstrata, which allows us to compute the correlators perturbatively. * bchen01, houjue, wukongjiaozi@pku.edu.cn

“…There is a long history of such consistent truncations [5][6][7][8][9][10][11], however, in [12], this work was extended to include extra tensor multiplets. These extra degrees of freedom are essential if one is to capture a subset of superstrata -a particularly important class of microstate geometries [13][14][15][16][17][18][19][20].…”

We analyze the BPS equations in the “superstratum sector” of three-dimensional gauged supergravity. We obtain multi-parameter supersymmetric solutions that include elliptical deformations of the supertubes that underlie standard superstrata. We uplift the three-dimensional solutions to obtain the corresponding six-dimensional geometries. This yields new families of elliptically-deformed, ambi-bolar hyper-Kähler geometries in four dimensions with a non-tri-holomorphic U(1) isometry. We also find a new family of scaling superstrata whose S-dual lives entirely within the NS-sector of supergravity, and will thus be more amenable to exact analysis using string probes. In all these new superstrata, including the scaling ones, if the momentum charge is non-zero we find that the ellipse stays away from the degeneration locus in which the ellipse becomes flat.

Multicenter superstrata

Abstract: We construct a new class of superstrata, the regular supergravity solutions describing the microstates of D1-D5-P black holes. Our solutions are obtained by adding momentum charge to the D1-D5 geometries based on multiple concentric Kaluza-Klein monopoles.
