A bstract Near the horizon of extremal charged black holes, an accidental symmetry is known to act on zero-temperature perturbations, transforming them into finite-temperature ones. In this paper, we uncover corresponding vacuum Einstein equation near spinning holes. To do so, first devise a new method deriving AdS 2 × S near-horizon geometry extreme Reissner-Nordström, using scaling coordinate transformation that unifies limits and near-extremal holes in way regular at zero temperature. We...

Extremal black holes have vanishing Hawking temperatures. In this paper, we argue that for asymptotically anti--de Sitter (AdS) holes, at extremality, a particular class of correlators in the dual conformal field theory can exhibit exponential, maximally chaotic growth with nonvanishing temperature. Our approach, is twofold. First, geometrically investigate modes are responsible chaos. Second, study dynamics probe string to capture chaos world sheet correlators. For rotating...

In this article, we explicitly demonstrate that, for a sufficiently generic class of examples, an open string embedded in AdS-background yields effective Schwarzian action and, the semi-classical description, fluctuation modes couple to sector. This leads maximal chaos, observed degrees freedom, irrespective gravitational background. corresponds dynamics quark-like freedom strongly coupled large N_c gauge theory. We also resulting from inherent D-brane horizon, by computing four-point...

The dynamics of a probe brane in given gravitational background is governed by the Dirac-Born-Infeld action. corresponding open string metric arises naturally studying fluctuations on probe. In Gauge-String duality, it known that presence constant electric field worldvolume probe, acquires an event horizon and therefore fluctuation modes experience effective temperature. this article, we bring together various properties such system to formal definition subsequent narration thermodynamics...

The open string metric arises kinematically in studying fluctuations of degrees freedom on a D-brane. An observer, living probe D-brane, can send signals through the spacetime by using such probe, that propagate accordance with which is conformal to metric. Event horizons emerge when one considers D-brane an electric field its worldvolume. Here, we emphasize role and investigate, details, causal structure resulting event horizon demonstrate, among other things, close similarities usual black...

It has recently been reported that certain thin timelike shells undergo oscillatory motion in AdS. In this paper, we compute two-point function of a probe field the geodesic approximation such an oscillating shell background. We confirm exhibits behaviour following shell. show similar dynamics is possible when perfect fluid on polytropic equation state. Moreover, ball like configurations AdS also exhibit and comment how solution can be smoothly matched to appropriate exterior solution....
