We extend previous techniques for calculations of transplanckian-energy stringstring collisions to the high-energy scattering of massless closed strings from a stack of N Dp-branes in Minkowski spacetime. We show that an effective non-trivial metric emerges from the string scattering amplitudes by comparing them against the semiclassical dynamics of high-energy strings in the extremal p-brane background. By changing the energy, impact parameter and effective open string coupling λ = gN , we are able to explore various interesting regimes and to reproduce classical expectations, including tidal-force excitations, even beyond the leading-eikonal approximation.

“…The asymptotically flat part is directly related to the description of the microstate in terms of D1 and D5-branes. As shown in [35][36][37][38] it is possible to use the worldsheet CFT describing the open strings stretched between the D-branes to derive the long distance behaviour of the various supergravity fields, including the multipole terms which are absent in the black hole geometry. In this paper we will not pursue this point of view at the quantitative level.…”

Abstract:We describe how to obtain the gravity duals of semiclassical states in the D1-D5 CFT that are superdescendants of a class of RR ground states. On the gravity side, the configurations we construct are regular and asymptotically reproduce the 3-charge D1-D5-P black hole compactified on S 1 × T 4 . The geometries depend trivially on the T 4 directions but non-trivially on the remaining 6D space. In the decoupling limit, they reduce to asymptotically AdS 3 × S 3 × T 4 spaces that are dual to CFT states obtained by acting with (exponentials of) the operators of the superconformal algebra. As explicit examples, we generalise the solution first constructed in arXiv:1306.1745 and discuss another class of states that have a more complicated dual geometry. By using the free orbifold description of the CFT we calculate the average values for momentum and the angular momenta of these configurations. Finally we compare the CFT results with those obtained in the bulk from the asymptotically M 1,4 × S 1 × T 4 region.

“…In this paper we will follow the approach of [19][20][21] and use the microscopic description of the bound state in terms of D-branes and open string states to derive the geometric properties of 3-charge microstates in particular limits. The basic idea of this approach is that the couplings of the bound state with the massless closed string sector of the theory (i.e.…”

“…Physically this closed string is the probe used to explore the backreacted geometry. In [19][20][21] this probe was always taken to have zero momentum in all compact directions. Of course, the information derived in this way cannot distinguish between localized or smeared configurations and the supergravity solutions derived could be interpreted entirely in a (non-minimal) five-dimensional supergravity [22].…”

We study a particular class of D-brane bound states in type IIB string theory (dubbed "superstrata") that describe microstates of the 5D Strominger-Vafa black hole. By using the microscopic description in terms of open strings we probe these configurations with generic light closed string states and from there we obtain a linearized solution of six-dimensional supergravity preserving four supersymmetries. We then discuss two generalizations of the solution obtained which capture different types of non-linear corrections. By using this construction, we can provide the first explicit example of a superstratum solution which includes the effects of the KK-monopole dipole charge to first order.
