Research Abstract |
We have analyzed a property and stability of new type of black holes, which do not belong to the Kerr-Newman family. In a unified theory of fundamental interactions, we usually expect non-Abelian gauge fields, which provide us new types of non-trivial structure like a monopole and new black holes. We have classified those black holes and presented a unified picture. We have also shown that the stability of those black holes is understood by a catastrophe theory, when the entropy of a black hole is regarded as the potential function. The qunatum radiation process of black holes has also been studied in theories with a dilaton field, which is inspired by a unified theory. A superstring model turns out to be critical in a sense that the energy flux of Hawking radiation diverges if the dilaton coupling with U (1) gauge field is larger than that of the superstring model.
