Black Hole Evaporation in Noncommutative Spacetime

A toy model based upon the q-deformation description for studying the radiation spectrum of black hole is proposed. The starting point is to try to consider the spacetime noncommutativity and to realize it by using a qdeformation algebraic technique. We calculated the radiation spectrum of Schwarzschild black hole in this framework. The new distribution deviates from the standard thermal spectrum evidently. The result indicates that some correlation effect will be introduced to the system if the noncommutativity is taken into account. The further argument implies that the result seems consistent with the UV/IR correspondence in superstring.
