“…At r ∼ a, there is a momentum wave that supports the geometry which smoothly caps off at r = 0. For studies of various physical aspects of this solution, see [42,44,79,[82][83][84][85][86][87][88][89][90], some of which are reviewed in section 5.…”

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

“…Many works were done in this direction within holographic contexts, for example, dealing with Brownian motion [18][19][20][21][22][23][24][25], fluctuation or dissipation [26][27][28][29][30][31][32], drag forces [33][34][35][36][37][38][39][40], and related topics [41][42][43][44][45][46][47]. In particular, de Boer et al studied the Brownian motion in a CFT described from AdS black holes [18].…”

Fluctuation and dissipation from a deformed string/gauge duality model

Using a Lorentz invariant deformed string/gauge duality model at finite temperature we calculate the thermal fluctuation and the corresponding linear response, verifying the fluctuation-dissipation theorem. The deformed AdS 5 is constructed by the insertion of an exponential factor expðk=r 2 Þ in the metric. We also compute the string energy and the mean square displacement in order to investigate the ballistic and diffusive regimes. Furthermore, we have studied the dissipation and the linear response in the zero temperature scenario.

“…Drag force is a characteristic phenomenon that occurs in AdS black holes: an open string, dual to a heavy quark, moving in thermal radiation of black holes, dual to a quark-gluon plasma (QGP), experiences a drag from the medium. In the case of BTZ black holes, it was studied in [51] and, more recently, further generalized in [52] to horizonless microstate geometries [53,54]. Based on an observation made in [25], we expect that the effect of the TT deformation is a renormalization of propagation speed in the speed dependence of the drag force.…”

Random boundary geometry and gravity dual of $$ T\overline{T} $$ deformation

We study the random geometry approach to the $$ T\overline{T} $$ T T ¯ deformation of 2d conformal field theory developed by Cardy and discuss its realization in a gravity dual. In this representation, the gravity dual of the $$ T\overline{T} $$ T T ¯ deformation becomes a straightforward translation of the field theory language. Namely, the dual geometry is an ensemble of AdS3 spaces or BTZ black holes, without a finite cutoff, but instead with randomly fluctuating boundary diffeomorphisms. This reflects an increase in degrees of freedom in the renormalization group flow to the UV by the irrelevant $$ T\overline{T} $$ T T ¯ operator. We streamline the method of computation and calculate the energy spectrum and the thermal free energy in a manner that can be directly translated into the gravity dual language. We further generalize this approach to correlation functions and reproduce the all-order result with universal logarithmic corrections computed by Cardy in a different method. In contrast to earlier proposals, this version of the gravity dual of the $$ T\overline{T} $$ T T ¯ deformation works not only for the energy spectrum and the thermal free energy but also for correlation functions.
