| Research Abstract |
Matrix models are very promising tools to investigate the microscopic structure of space-time. We have reproduced perturbative string theory from matrix models in 2 dimensional non-commutative space-time. We have confirmed the gauge/gravity duality in 10 dimensional black-hole and dual matrix quantum mechanics. We have universally understood the Hawking radiation from quantum anomaly at the Horizon. In de Sitter space-time with cosmological horizon, we have investigated the particle production effects in interacting field theory. We have shown the result is consistent with unitarity. We have thus obtained these important results. The most remarkable point is that we have uncovered connections with wider research fields such as non-equilibrium physics.
