Configurational temperatures: a novel approach to dusty plasmas — •Michael Himpel and André Melzer — University Greifswald, Germany

In dusty plasma systems, the kinetic temperature is often used to characterize dynamical processes of particle clusters. An experimental drawback of this temperature definition is, that the velocities of the particles have to be known, which implies the application of fast imaging techniques and which is often problematic.

A different definition of the temperature, called configurational temperature, can be used to determine the temperature of the particle system on basis of the particle positions and interaction forces instead of its velocities. Here, we show the application of this temperature definition to finite and large dust clusters in 2D and 3D.
