Black Hole Microstates and String Theory

• Masaki Shigemori

Room: Jean Sacton seminar room (1G003) The black hole is one of the the most intriguing objects in our universe. Although its classical properties are well understood, its quantum, microscopic nature is poorly understood. String theory has been successful in explaining certain quantum aspects of black holes, but there still remain many unresolved problems. In this talk, I will first review the studies of black holes in string theory, in particular recent developments about what microscopic structure may be underlying macroscopic black holes. Then, I will discuss more recent developments in realizing black hole microstates in the framework of supergravity and string theory generalization thereof, as non-trivial configurations of string theory objects.
