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.

Academic Significance and Societal Importance of the Research Achievements |
ブラックホールの微視的物理は現代物理学の未解明問題の1つであり、そのためには量子力学と一般相対性理論を統一する理論である弦理論が鍵である。本研究は、ブラックホールの微視的状態を、弦理論の低エネルギー極限である超重力理論を用いて具体的に構成しようというものである。具体的な微視的状態が得られれば、それを用いてブラックホールの微視的物理を具体的に調べることが可能となり、未解明問題が解決できると期待される。また、近年、重力波の観測などによりブラックホールの直接観測が可能となった。ブラックホールの微視的理解は、観測可能な予言につながる可能性も秘めている。
