Dusty plasmas can be found in many places both in space and in the laboratory. Due to their special properties, dust acoustic waves can propagate inside these plasmas like sound waves in air, and can be studied with the naked eye or with standard video cameras. The Ruhr-Universitaet-Bochum physicists Prof. Dr. Dr. h.c. Padma Kant Shukla and Dr. Bengt Eliasson from the Faculty of Physics and Astronomy have published a model with which they describe how large amplitude dust acoustic waves in dusty plasmas behave.
