Five dimensional non-supersymmetric black holes and strings (original) (raw)

We classify all N=2 rigid supersymmetric backgrounds in four dimensions with both Lorentzian and Euclidean signature that preserve eight real supercharges, up to discrete identifications. Among the backgrounds we find specific warpings of S^3 x R and AdS_3 x R, AdS_2 x S^2 and H^2 x S^2 with generic radii, and some more exotic geometries. We provide the generic two-derivative rigid vector and hypermultiplet actions and analyze the conditions imposed on the special Kahler and hyperkahler target spaces.

We continue the effort of defining and evaluating the quantum entropy function for supersymmetric black holes in 4d mathcalN\mathcal{N}mathcalN N = 2 gauged supergravity, initiated in [1]. The emphasis here is on the missing steps in the previous localization analysis, mainly dealing with one-loop determinants for abelian vector multiplets and hypermultiplets on the non-compact space ℍ 2 × Σg with particular boundary conditions. We use several different techniques to arrive at consistent results, which have a most direct bearing on the logarithmic correction terms to the Bekenstein-Hawking entropy of said black holes.

We study supersymmetric solutions in four-dimensional N=6N=6N=6 gauged supergravity with SO(6)SO(6)SO(6) gauge group. There is a unique N=6N=6N=6 supersymmetric AdS_4AdS_4AdS4 vacuum with SO(6)SO(6)SO(6) symmetry dual to an N=6N=6N=6 SCFT in three dimensions. We find a number of domain walls interpolating between this AdS4AdS_4AdS_4 vacuum and singular geometries in the IR with SO(2)timesSO(4)SO(2)\times SO(4)SO(2)timesSO(4), U(3)U(3)U(3), SO(3)SO(3)SO(3) and SO(2)timesSO(2)timesSO(2)SO(2)\times SO(2)\times SO(2)SO(2)timesSO(2)timesSO(2) symmetries. The SO(3)SO(3)SO(3) case admits N=6N=6N=6 or N=2N=2N=2 solutions depending on whether the pseudoscalars are present or not. On the other hand, all the remaining solutions preserve N=6N=6N=6 supersymmetry. These solutions describe RG flows from the N=6N=6N=6 SCFT to non-conformal field theories driven by mass deformations. In particular, the SO(2)timesSO(4)SO(2)\times SO(4)SO(2)timesSO(4) solution is in agreement with the previously known mass deformations of the dual N=6N=6N=6 SCFT. We also give a supersymmetric Janus solution with SO(2)timesSO(4)SO(2)\times SO(4)SO(2)timesSO(4) symmetry, describing two-dimensional conformal defects in the N=6N=6N=6 SCF...

We study the thermodynamics of the recently-discovered non-extremal charged rotating black holes of gauged supergravities in five, seven and four dimensions, obtaining energies, angular momenta and charges that are consistent with the first law of thermodynamics. We obtain their supersymmetric limits by using these expressions together with an analysis of the AdS superalgebras including R-charges. We give a general discussion
