Effects of Hawking radiation in monopole black hole background

چکیده
We study the Hawking radiation in a monopole black hole background in SO(3) Einstein-Yang-Mills-Higgs system. We only consider a massless scalar field which does not couple with the Yang-Mills field or Higgs field around the black hole. Starting from a Reissner-Nortström black hole, and assuming that it transits into a monopole black hole at a critical point, we find that the evaporation rate will increase continuously or discontinuously according to the type of phase transition, that is either second order or first order, respectively. We also discuss differences in evaporating rate between a monopole black hole and a Reissner-Nortström black hole. The results are such that although the transmission amplitude Γ for a monopole black hole becomes smaller than electronic mail:[email protected] electronic mail:[email protected]

Hawking radiation of charged particles as tunneling from Reissner-Nordström-de Sitter black holes with a global monopole
Applying Parikh’s semi-classical tunneling method, we consider Hawking radiation of the charged massive particles as a tunneling process from the Reissner-Nordströmde Sitter black hole with a global monopole. The result shows that the tunneling rate is related to the change of Bekenstein-Hawking entropy and the radiant spectrum is not a pure thermal one, but is consistent with an underlying uni...

We derive the metric for a Schwarzschild black hole with global monopole charge by relaxing asymptotic flatness of the Schwarzschild field. We then study the effect of global monopole charge on particle orbits and the Hawking radiation. It turns out that existence, boundedness and stability of circular orbits scale up by (1 − 8πη2)−1, and the perihelion shift and the light bending by (1−8πη2)−3...

متن کاملBTZ Black Holes and Hawking Radiation
Hawking radiation emanating from a two-dimensional analogue of BTZ black holes is viewed as a tunnelling process. Two dimensional BTZ black holes (AdS(2) included) are treated as dynamical backgrounds in contrast to the standard methodology where the background geometry is fixed when evaluating Hawking radiation. This modification to the geometry gives rise to a nonthermal part in the radiation...

We calculate the absorption coefficient of scalar field on the background of the two-dimensional AdS black hole, which is of relevance to Hawking radiation. For the massless scalar field, we find that there does not exist any massless radiation. electronic address:[email protected] electronic address:[email protected] electronic address:[email protected] 1 There has been mu...
