“…The simplicity of the susy AdS soliton make us conjecture that these 1/2 BPS solutions can be generalized to have different charges by the introduction of running scalars in D = 4 and D = 5 gauged supergravity [23,[37][38][39]. Furthermore, we believe that this susy AdS soliton should also be part of the spectrum of any gauged supergravity in any dimension that contains a consistent supersymmetric truncation with a U(1) gauge field.…”

We study Lorentzian supersymmetric configurations in D = 4 and D = 5 gauged $$ \mathcal{N} $$ N = 2 supergravity. We show that there are smooth 1/2 BPS solutions which are asymptotically AdS4 and AdS5 with a planar boundary, a compact spacelike direction and with a Wilson line on that circle. There are solitons where the S1 shrinks smoothly to zero in the interior, with a magnetic flux through the circle determined by the Wilson line, which are AdS analogues of the Melvin fluxtube. There is also a solution with a constant gauge field, which is pure AdS. Both solutions preserve half of the supersymmetries at a special value of the Wilson line. There is a phase transition between these two saddle-points as a function of the Wilson line precisely at the supersymmetric point. Thus, the supersymmetric solutions are degenerate, at least at the supergravity level. We extend this discussion to one of the Romans solutions in four dimensions when the Euclidean boundary is S1× Σg where Σg is a Riemann surface with genus g > 0. We speculate that the supersymmetric state of the CFT on the boundary is dual to a superposition of the two degenerate geometries.

“…In this case, we set ϕ 1 = ϕ 3 = 0. The STU model then reduces to the n = 1 model, coinciding with our (57). The Duff-Liu configuration can be recovered from our solution provided either the magnetic or the electric charges are set to zero.…”

“…Scalar self-interactions could be relevant for dynamic and thermodynamic stability of the configuration: naively, we can imagine the condition for the existence of hairy solutions as if the self-interaction of the scalar and the gravitational interaction were to combine such that the near-horizon hair did not collapse into the black hole, while the far-region hair did not escape to infinity 3. These new solutions generalize the uncharged configurations of[47,51,56,57].…”

We review a special class of N=2 supergravity model that interpolates all the single-dilaton truncations of the maximal SO(8) gauged supergravity. We also provide explicit non-extremal, charged black hole solutions and their supersymmetric limits, asymptotic charges, thermodynamics and boundary conditions. We also discuss a suitable Hamilton–Jacobi formulation and related BPS flow equations for the supersymmetric configurations, with an explicit form for the superpotential function. Finally, we briefly analyze certain models within the class under consideration as consistent truncations of the maximal, N=8 gauged supergravity in four dimensions.

“…which corresponds to AdS invariant boundary conditions [4,41], namely a triple trace deformation in the boundary theory. Hence, the boundary conformal symmetry is preserved and the black hole mass can be extracted from the asymptotic expansion of the spacetime [4,11,32,38,42,43]. The expansion of metric (4.1) explicitly reads:…”

“…1 Static hairy single-scalar black holes within these models were recently constructed and studied in [4,11,17]. In the BPS limit [4], such solutions are related to the class of black holes considered in [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Hairy black hole solutions in higher dimensions were considered in [33], generalizing those found in [34].…”

In this paper we prove that the four-dimensional hyperbolic supersymmetric black holes can be unstable in the canonical ensemble. To this end, we work with an infinite class of $$ \mathcal{N} $$ N = 2 supergravity theories interpolating between all the single dilaton truncations of the SO(8) gauged $$ \mathcal{N} $$ N = 8 supergravity. Within these models, we study electrically charged solutions of two different kinds: supersymmetric hairy and extremal non-supersymmetric Reissner-Nordström black holes. We consider these solutions within the same canonical ensemble and show that, for suitable choices of the parameters defining the $$ \mathcal{N} $$ N = 2 model, the supersymmetric solution features a higher free energy than the non-supersymmetric one. In the absence of additional selection rules, this would imply an instability of the supersymmetric configuration, hinting towards a possible supersymmetry breaking mechanism.
