The
focus of this article is to study the effect of diffusion on the
dynamics of distributions of particles adsorbed on a surface. The
dynamics of particle distributions can be viewed as the change of
configurations with time. The configurations are created by adsorption,
desorption, or diffusion. This kind of study is not only important for
surface-science studies, but it is also very useful in the study of
complex system in general.
One
important aspect of political dynamics is the fact that people are
taking sides. There are times where the available sides are very
limited, and the people's preferences are very clear. But there are also
times where not only the number of sides is not clear, but the people
also keep on changing sides all the time. In our simulation, we define
the condition where the number of political sides are limited, and the
people's choice is very clear and consistent as the situation where the
temperature is low. On the other hand, we define the the situation when
the people's choice is always changing, and the preferential attachment
is many, as the situation where the temperature is high. This situation
is illustrated by Fig. 1.
In
many studies it has been shown that connectivity actually increase the
probability of damage spreading, hence contributing to the instability
of the system. In this report we take a different stand by making a
differentiation between positive and negative connectivity.
