AbstractAbstract
[en] We construct the most general static regular, non-gauge spin-3/2 perturbations on the Majumdar-Papapetrou background for two black holes. The construction applies a limiting procedure by combining Killing spinors and spacetime perturbations. The supercharge associated with the spin-3/2 field is proportional to the difference of the mass parameters, implying that a system of two equal black holes has zero supercharge. (Author)

AbstractAbstract
[en] In the context of CA conjecture for holographic complexity, we study the action growth rate at late time approximation for general quadratic curvature theory of gravity. We show how the Lloyd’s bound saturates for charged and neutral black hole solutions. We observe that a second singular point may modify the action growth rate to a value other than the Lloyd’s bound. Moreover, we find the universal terms that appear in the divergent part of complexity from computing the bulk and joint terms on a regulated WDW patch.

AbstractAbstract
[en] Time dependent boundary conditions influence quantum fields and lead to particle production. This particle production is given in the environment of black holes and gives rise to the blackbody radiation, calculated first by Hawking. By this effects black holes end up in explosions. (WL)

AbstractAbstract
[en] We examine the problem of stability of Einstein Yang-Mills black holes, studied recently by Straumann and Zhou in the framework of linearized perturbation technique. It is pointed out that the existence of the exponentially growing radial mode, found by Straumann and Zhou, does not necessarily signal instability because the unstable mode may not be acceptable due to its singular behaviour at the horizon. In particular, we show that the lowest-energy colored black hole is linearly stable against radial perturbations. We show also that the SU(2) Reissner-Nordstroem solution with mass M and magnetic charge 1/g is dynamically stable if the dimensionless constant G1/2gM is bigger than some critical value.

AbstractAbstract
[en] By considering the dual Liouville theory emerging in the near-horizon limit, we study the thermodynamics of general rotating black hole with four charges in four dimensions. Both the black hole entropy and temperature are found to agree with the gravitational expectations. The relations between the new Liouville formalism and the anomaly approach are also discussed.
