چکیده
Black hole spontaneous scalarization has been attracting more and attention as it circumvents the well-known no-hair theorems. In this work, we study in Einstein-scalar-Gauss-Bonnet theory with a probe scalar field black background different curvatures. We first signal of positive curvature spacetimes. The AdS spacetime could be formed easier than that flat case. Then, investigate around holes negative zero Comparing cases, near much to emerge. And case, is most difficult bounded horizon.

On Black Hole Horizon Fluctuations
A study of the high angular momentum particles ’atmosphere’ near the Schwarzschild black hole horizon suggested that strong gravitational interactions occur at invariant distance of the order of 3 √ M . We present a generalization of this result to the Kerr-Newman black hole case. It is shown that the larger charge and angular momentum black hole bears, the larger invariant distance at which st...
متن کاملUniversal near - horizon conformal structure and black hole entropy Sayan
It is shown that a massless scalar probe reveals a universal near-horizon conformal structure for a wide class of black holes, including the BTZ. The central charge of the corresponding Virasoro algebra contains information about the black hole. With a suitable quantization condition on the central charge, the CFT associated with the black hole in our approach is consistent with the recent obse...

متن کاملSpacetime structure of an evaporating black hole in quantum gravity
The impact of the leading quantum gravity effects on the dynamics of the Hawking evaporation process of a black hole is investigated. Its spacetime structure is described by a renormalization group improved Vaidya metric. Its event horizon, apparent horizon, and timelike limit surface are obtained taking the scale dependence of Newton’s constant into account. The emergence of a quantum ergosphe...
متن کاملBlack Hole Horizon and Turns it Singular
We present a static solution for d = 2 critical string theory including the tachyon T but not its potential V (T ). This solution thus incorporates tachyon back reaction and, when T = 0, reduces to the black hole solution. When T 6= 0 one finds that (1) the Schwarzschild horizon of the above black hole splits into two, resembling Reissner-Nordstrom horizons and (2) the curvature scalar develops...
