| Outline of Final Research Achievements |
Black holes are almost featureless macroscopically but, microscopically, they must be made of microstates with non-trivial structure. Some of such black-hole microstates are known to be described by “microstate geometries” -- smooth and horizonless solutions of classical gravity theory. In this research, we constructed various microstate geometries that describe microstates of black holes that appear in string theory. These microstate geometries are called “superstrata” and represent the most general class of microstate geometries ever constructed. The microstate geometries constructed in the current project provide indispensable tools that can be used to explore microscopic physics of black holes in a very concrete manner.
