 abstract = {We develop a framework for understanding the difference between strong
and fragile behavior in the dynamics of glass-forming liquids from the
properties of the potential energy landscape. Our approach is based on a
master equation description of the activated jump dynamics among the
local minima of the potential energy (the so-called inherent structures)
that characterize the potential energy landscape of the system. We study
the dynamics of a small atomic cluster using this description as well as
molecular dynamics simulations and demonstrate the usefulness of our
approach for this system. Many of the remarkable features of the complex
dynamics of glassy systems emerge from the activated dynamics in the
potential energy landscape of the atomic cluster. The dynamics of the
system exhibits typical characteristics of a strong supercooled liquid
when the system is allowed to explore the full configuration space. This
behavior arises because the dynamics is dominated by a few lowest-lying
minima of the potential energy and the potential energy barriers between
these minima. When the system is constrained to explore only a limited
region of the potential energy landscape that excludes the basins of
attraction of a few lowest-lying minima, the dynamics is found to
exhibit the characteristics of a fragile liquid.},
