Description
We perform numerical studies of the type IIB matrix model, which was proposed as a
nonperturbative formulation of superstring theory in 1996. In our study, we apply the
complex Langevin method in order to overcome the sign problem, which occurs in Monte
Carlo simulations. In particular, we investigate a scenario on how the signature of space-time
could be determined dynamically in this model and discuss the possibility of the emergence
of the (3+1)D expanding universe.
