What is it about?

We have shown the presence of chaos in the dynamical dust clusters of particles interacting via screened Coulomb potential confined by an external radial electric field.

Why is it important?

Understanding the dynamics of charged particles under certain conditions is essential for gaining efficiency in many plasma etching technologies. It is also interesting to note that for systems comprising particles interacting with attractive forces, such as gravitational force, one observes periodic dynamical configurations, e.g., planetary motion, etc. Here, in contrast, charged particles interacting with repulsive forces have been considered (which are confined by an external potential), and it has been demonstrated that they show nonperiodic chaotic dynamics.


I hope this article will give the reader an essence of some fundamental concepts of physics and chaos with dusty plasma as a testbed medium.
