“…Instead, it suggests that one must concentrate on supertube-like solutions as the superstratum. Our findings are also consistent with previous results on the D1-D5 orbifold conformal field theory, since only supertube-like solutions seem to admit a holographic description within this framework [63][64][65][66].…”

We systematically study all supersymmetric solutions of six-dimensional (2, 0) supergravity with a null isometry. In particular, every such solution with at least four real supersymmetries is also a supersymmetric solution of a (1, 0) theory preserving the same absolute amount of supersymmetry. This implies that no genuinely new solutions of this type can be found in this framework. The microstate geometries associated to supersymmetric black holes within Mathur's proposal are generically supersymmetric solutions of six-dimensional supergravity. A direct consequence of our result is that supersymmetric microstate geometries of single centre supersymmetric black holes should carry only one compact 3-cycle.

“…For small values of rH , the exponential decay lasts as long as r H Ry v 1, but in this regime, it does not become parametrically small. 18 For interesting recent work on CFT three-point function of one light and two similar heavy states see for example [52][53][54][55]. 19 Although this was not made explicit in [13], the calculation of the large momentum limit of the Wightman function also applies to microstate geometries that have long BTZ throats and small angular momentum.…”

We develop a new hybrid WKB technique to compute boundary-to-boundary scalar Green functions in asymptotically-AdS backgrounds in which the scalar wave equation is separable and is explicitly solvable in the asymptotic region. We apply this technique to a family of six-dimensional 1 8 -BPS asymptotically AdS 3 × S 3 horizonless geometries that have the same charges and angular momenta as a D1-D5-P black hole with a large horizon area. At large and intermediate distances, these geometries very closely approximate the extremal-BTZ × S 3 geometry of the black hole, but instead of having an event horizon, these geometries have a smooth highly-redshifted global-AdS 3 × S 3 cap in the IR. We show that the response function of a scalar probe, in momentum space, is essentially given by the pole structure of the highly-redshifted global-AdS 3 modulated by the BTZ response function. In position space, this translates into a sharp exponential black-hole-like decay for times shorter than N 1 N 5 , followed by the emergence of evenly spaced "echoes from the cap," with period ∼ N 1 N 5 . Our result shows that horizonless microstate geometries can have the same thermal decay as black holes without the associated information loss. arXiv:1905.05194v1 [hep-th]

“…Precision holography [37,48] indicates that, the relation between the mode coefficients b k,m,n 4 , b k,m,n 4 and the coherent state parameters A k,m,n , A k,m,n is not modified at higher order; they are simply proportional to each other. This suggests that coiffuring is the way preferred by CFT to fix the mode coefficients.…”

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
