Three-dimensional Gravity and Instability of AdS$_{3}$

Abstract: This is an extended version of my lecture at the LIII Cracow School of Theoretical Physics in Zakopane in which I presented the results of joint work with Piotr Bizoń [1] concerning (in)stability of the threedimensional anti-de Sitter spacetime.

“…In addition we have 7 irremovable secular resonances with quantum numbers found in the normal mode spectra ( 5) and ( 7), but that do not coincide with the data (12), { , m, p, ω} s = {6, 6, 1, 9/L}, {8, 6, 0, 9/L} ; { , m, p, ω} s = {8, 8, 2, 13/L}, {10, 8, 1, 13/L}, {12, 8, 0, 13/L} ; { , m, p, ω} v = {9, 8, 1, 13/L}, {11, 8, 0, 13/L} . (13) Here, the first line resonances are of the type 2ω 7 − ω7 = 9/L and coincide with those in the last column of Table II when we start with the single normal mode { , m, p, ω} v = {7, 6, 0, 9/L}. However, the second and third line resonances are of the type 2ω 7 − ω4 = 13/L and thus a consequence of the two-mode collision (12).…”

“…The top panel of figure 8 shows the turbulent energy cascade for the µ = √ 10 and = 0.02. While we cannot rule out that inverse cascades appear at lower amplitudes, we note that this initial data already appears to be in the perturbative regime, as Π 2 (t, x = 0) obeys the perturbative scaling law, 8 as we see in the bottom panel of figure 8. This suggests that AdS 5 may have smaller stable regions around single mode data than AdS 4 , at least for the values of µ we considered.…”

“…The original studies of massless scalar field matter have since been followed by studies of complex scalar fields [5] and modified theories of gravity [6]. Except when there is a mass gap in the black hole spectrum (such as AdS 3 [7,8] or AdS 5 Einstein-Gauss-Bonnet gravity [6]), these numerical studies have pointed to instability to horizon formation at arbitrarily small amplitudes for generic initial data, which occurs along with a cascade of energy into high frequency modes. On the other hand, certain initial data appear stable at low amplitudes, and additional types of initial data are the subject of some disagreement (see [9][10][11]).…”

“…We see that localization increases with dimension, and is least for d = 2 (AdS 3 ). In AdS 3 , numerical studies show a very fast transfer of energy to higher frequencies (in comparison to higher dimensions), yet no black hole formation [3], [4]. We speculate that at least part of the reason may be that the eigenfunctions localize the least in three dimensions.…”
