Abstract
We present numerical investigations of the dynamics on the energy landscape of a realistic model of the high-temperature ceramic a-Si3B3N7. Below a critical temperature Tc = 2000 K, the system is no longer in equilibrium, and we predict that the material has a glass transition in this temperature range at high pressure. Analyzing the two-time energy correlation function shows aging in this system, which is linked to the geometrical properties of the energy landscape.
