Anti-Evaporation of Black Holes in Bigravity
نویسنده
چکیده
We review properties of solutions in bigravity theory for a specific case where two metric tensors, gμν and fμν , satisfy proportional relation fμν = Cgμν . For this condition, we find that the solutions describing the asymptotically de Sitter space-time can be obtained and investigate the perturbation around the Schwarzschild–de Sitter solutions and corresponding anti-evaporation. We discuss the stability under special perturbations related to the anti-evaporation and the importance of the non-diagonal components of the metric in bigravity.

(Anti-)Evaporation of Schwarzschild-de Sitter Black Holes
We study the quantum evolution of black holes immersed in a de Sitter background space. For black holes whose size is comparable to that of the cosmological horizon, this process differs significantly from the evaporation of asymptotically flat black holes. Our model includes the one-loop effective action in the s-wave and large N approximation. Black holes of the maximal mass are in equilibriu...
متن کاملNUMBERING——— NUMBERING— DOESN’T Predictability in Quantum Gravity and Black Hole Evaporation
A possible resolution of the information loss paradox for black holes is proposed in which a phase transition occurs when the temperature of an evaporating black hole equals a critical value, Tc, and Lorentz invariance and diffeomorphism invariance are spontaneously broken. This allows a generalization of Schrödinger’s equation for the quantum mechanical density matrix, such that a pure state c...
متن کاملClassical and Semiclassical Properties of Extremal Black Holes with Dilaton and Modulus Fields
We discuss both classical and semiclassical properties of extremal black holes in theories where the dilaton and a modulus field are present. We find that the corresponding 2-dim geometry is asymptotically anti-de Sitter rather then asymptotically flat as in the purely dilatonic case. This fact has many important consequences, which we analyze at length, both for the classical behaviour and for...

متن کاملPrimordial black holes in braneworld cosmologies: Formation, cosmological evolution, and evaporation
We consider the population evolution and evaporation of primordial black holes in the simplest braneworld cosmology: Randall-Sundrum type II. We demonstrate that black holes forming during the high-energy phase of this theory ~where the expansion rate is proportional to the density! have a modified evaporation law, resulting in a longer lifetime and lower temperature at evaporation, while those...
