“…Upon dualizing the solution from type IIA string theory to the heterotic string, we will be able to compare the gravity and dual CFT results [27]. We would also like to apply our construction to the more intricate cohomogeneity-2 case, in particular to the smooth horizonless microstate geometries [28,29] that have the same asymptotic structure at infinity as a given supersymmetric black hole of the same mass, charges and angular momenta. The microstate geometries also admit an AdS 3 ×S 3 throat.…”

We construct the first rotating string solution in 6-dimensional Einstein-Gauss-Bonnet supergravity, carrying both electric and magnetic charges. By embedding the known rotating string solution of the 2-derivative theory into 6-dimensional off-shell supergravity, the Killing spinors associated with the underlying supersymmetry can be made off-shell and are universal to all off-shell supergravity models based on the same field content. The near-horizon geometry is S 3 fibred over the extremal BTZ black hole, locally isomorphic to AdS 3 ×S 3 . We compute the higher-derivative corrections to the Brown-Henneaux central charges in a particular R + R 2 model resulting from K3 compactification of type IIA string theory.

“…If we solve the zeroth layer, the remaining two layers can be written as linear differential equations on B. In practice, in most of the explicit superstratum solutions in the literature, it is assumed that the B is flat R 4 or a Gibbons-Hawking space [43,71,72], and that β is independent of v.…”

We give a survey of the present status of the microstate geometries called superstrata. Superstrata are smooth, horizonless solutions of six-dimensional supergravity that represent some of the microstates of the D1-D5-P black hole in string theory. They are the most general microstate geometries of that sort whose CFT dual states are identified. After reviewing relevant features of the dual CFT, we discuss the construction of superstratum solutions in supergravity, based on the linear structure of the BPS equations. We also review some of recent work on generalizations of superstrata and physical properties of superstrata. Although the number of superstrata constructed so far is not enough to account for the black-hole entropy, they give us valuable insights into the microscopic physics of black holes.where J 3 0 is a generator of SU (2) L ∈ SO(4) coming from the rotational symmetry in the directions transverse to the D-branes.3 The CFT dual states of superstrata based on the five-dimensional multi-center solutions with two centers

“…The simplest models that give smooth superstrata involve coupling to two tensor multiplets. It is also possible [13], in certain circumstances to compactify the theory on a circle direction inside the M 1,4 ×S 1 , the theory then reduces to a 5-dimensional N = 2 supergravity coupled to three vector multiplets. This compactification is nothing more than a standard Kaluza-Klein reduction, which ensures the BPS equations in each dimension are related.…”

We construct the most general single-mode superstrata in 5 dimensions with ambipolar, two centered Gibbons Hawking bases, via dimensional reduction of superstrata in 6 dimensions. Previously, asymptotically AdS 3 ×S 2 5-dimensional superstrata have been produced, giving microstate geometries of black strings in 5 dimensions. Our construction produces asymptotically AdS 2 × S 3 geometries as well, the first instances of superstrata describing the microstate geometries of black holes in 5 dimensions. New examples of superstrata with separable massless wave equations in both 5 and 6 dimensions are uncovered. A Z 2 symmetry which identifies distinct 6-dimensional superstrata when reduced to 5 dimensions is found. Finally we use the mathematical structure of the underlying hyper-Kähler bases to produce prepotentials for the superstrata fluxes in 5 dimensions and uplift them to apply in 6 dimensions as well.
