Quantitative Analysis of Physical and Statistical Properties of Flocks.

Flocking behavior is a common phenomenon in nature in the form of, for instance, flocks
of birds or schools of fish. Making the assumption that the members of a flock can be
considered a system of interacting particles it is possible to use methods from statistical
physics to quantitatively analyze flocks and their properties. This way, a flock can exist in
various thermodynamic phases and exhibit phase transitions depending on changes within
the flock. In this report the flock analysis is performed with the help of a model originally
created by Vicsek et al. The model is governed by certain parameters controlling the
interaction between individual flock members. From the results it is possible to see that
even small deviations in these parameter values can lead to great phase alterations as well
as phase transitions, which strengthens to the assumption that a flock can be considered
a system of particles.
