    A cornucopia of AdS5 vacua 
    Bobev, Nikolay; Fischbacher, Thomas; Gautason, Fridrik F; Pilch, Krzysztof (Springer Science and Business Media LLC, 2020-07-01)
    We report on a systematic search for AdS5 vacua corresponding to critical points of the potential in the five-dimensional N = 8 SO(6) gauged supergravity. By employing Google’s TensorFlow Machine Learning library, we find the total of 32 critical points ...

    Holographic interfaces in N = 4 SYM: Janus and J-folds 
    Bobev, Nikolay; Gautason, Fridrik F; Pilch, Krzysztof; Suh, Minwoo; van Muiden, Jesse (Springer Science and Business Media LLC, 2020-05-01)
    We find the holographic dual to the three classes of superconformal Janus interfaces in N = 4 SYM that preserve three-dimensional N = 4, N = 2, and N = 1 supersymmetry. The solutions are constructed in five-dimensional SO(6) maximal gauged supergravity ...

    Holographic uniformization and black hole attractors 
    Bobev, Nikolay; Gautason, Fridrik F; Parmentier, Klaas (Springer Science and Business Media LLC, 2020-06-01)
    We establish an attractor mechanism for the horizon metric of asymptotically locally AdS4 supersymmetric black holes. The horizon is a smooth Riemann surface with arbitrary metric at asymptotic infinity which is fixed to the constant curvature metric ...

    Page curve for an evaporating black hole 
    Gautason, Fridrik F; Schneiderbauer, Lukas; Sybesma, Watse; Thorlacius, Larus (Springer Science and Business Media LLC, 2020-05-01)
    A Page curve for an evaporating black hole in asymptotically flat spacetime is computed by adapting the Quantum Ryu-Takayanagi (QRT) proposal to an analytically solvable semi-classical two-dimensional dilaton gravity theory. The Page time is found to ...

    Wrapped branes and punctured horizons 
    Bobev, Nikolay; Bomans, Pieter; Gautason, Fridrik F (Springer Science and Business Media LLC, 2020-06-01)
    Large classes of AdSpsupergravity backgrounds describing the IR dynamicsofp-branes wrapped on a Riemann surface are determined by a solution to the Liouvilleequation. The regular solutions of this equation lead to the well-known wrapped branesupergravity ...
