“…Indeed, using deformations of the CFT, one can compute transitions from this state to bosonic and fermionic excitations. These transitions thus appear to be CFT signatures of tidal excitations of probes in the bulk [35,36]. As a guiding principle, this suggests that a probe moving within the superstrata geometries should experience tidal excitations not only along the S 3 , as shown in [33], but also along the T 4 directions, thus motivating the investigation of this paper.…”

“…Recent work [35,36] suggests that this amplitude should grow in time. This growth indicates the transfer of energy from a single bosonic mode to multiple modes in the final state which share the initial energy amongst themselves.…”

Tidal effects in capped geometries computed in previous literature display no dynamics along internal (toroidal) directions. However, the dual CFT picture suggests otherwise. To resolve this tension, we consider a set of infalling null geodesics in a family of black hole microstate geometries with a smooth cap at the bottom of a long BTZ-like throat. Using the Penrose limit, we show that a string following one of these geodesics feels tidal stresses along all spatial directions, including internal toroidal directions. We find that the tidal effects along the internal directions are of the same order of magnitude as those along other, non-internal, directions. Furthermore, these tidal effects oscillate as a function of the distance from the cap — as a string falls down the throat it alternately experiences compression and stretching. We explain some physical properties of this oscillation and comment on the dual CFT interpretation.

“…This slow scrambling can also be seen in the dual two-dimensional CFT [51]. Relatedly, tidal forces have been computed in superstratum solutions [52], and analyzed in the holographically dual CFT [53]. Chaotic behaviour has also been observed at the rim of black hole and microstate geometry shadows [54].…”

Gravitational solutions involving shockwaves have attracted significant recent interest in the context of black holes and quantum chaos. Certain classes of supersymmetric two-charge black hole microstates are described by supergravity solutions containing shockwaves, that are horizonless and smooth away from the shockwave. These configurations have been used to describe how black hole microstates absorb and scramble perturbations. In this paper we construct the first family of asymptotically flat supersymmetric three-charge microstate solutions that contain shockwaves. We identify a family of holographically dual states of the D1-D5 CFT and show that these pass a set of tests, including a precision holographic test. We find precise agreement between gravity and CFT. Our results may prove useful for constructing more general families of black hole microstate solutions.

“…(iii) The ultra-relativistic infall speeds of infalling particles, combined with the tiny deviations of microstate geometries from black holes, causes a probe to experience string-scale tidal forces [115][116][117][118][119][120][121][122]. Indeed, a similar process was already evident in ultra-relativistic string scattering [123][124][125][126].…”

The black-hole information paradox provides a stringent test of would-be theories of quantum gravity. String theory has made significant progress toward a resolution of this paradox, and has led to the fuzzball and microstate geometry programs. The central thesis of these programs is that only string theory has sufficiently many degrees of freedom to resolve black-hole microstructure, and that horizons and singularities are artifacts of attempting to describe gravity using a theory that has too few degrees of freedom to resolve the physics. Fuzzballs and microstate geometries recast black holes within string theory as horizonless and singularity-free objects that not only resolve the paradox but provide new insight into the underlying microstructure. We give an overview of this approach, summarize its current status and describe future prospects and insights that are now within reach.
