complex plasmas
Complex plasmas are distinct from conventional plasmas by the presence ofComplex plasmas are distinct from conventional plasmas by the presence of• additional plasma constituents,• by particle correlations,• by interactions with solid surfaces,by interactions with solid surfaces,which decisively influence the behavior of the plasma and provide importantand novel properties.
Recent developments demand a redefinition and thematic extension of theclassical plasma concept.
Complex plasma systems which contain, for example, colloidalnano/microscopic particles (dust) have recently been widely discussed in thephysics and chemistry of plasmas, ionized gases, space physics andastrophysics, plasma diagnostics, as well as in materials research andengineering.

Ludwig, Springer, 2010.Complex plasmas differ from traditional plasmas in many ways: these are low-Complex plasmas differ from traditional plasmas in many ways: these are lowtemperature high pressure systems containing nanometer to micrometer sizeparticles which may be highly charged and strongly interacting. The particlesmay be chemically reacting or be in contact with solid surfaces, and thel h b h i h i i i h l delectrons may show quantum behaviour. These interesting properties have led
to many applications of complex plasmas in technology, medicine and science.Yet complex plasmas are extremely complicated, both experimentally andtheoretically, and require a variety of new approaches which go beyondtheoretically, and require a variety of new approaches which go beyondstandard plasma physics courses. This book fills this gap presenting anintroduction to theory, experiment and computer simulation in this field. Basedon tutorial lectures at a very successful recent Summer Institute, the

Focus on Complex (Dusty) Plasmas

The research field of complex (dusty) plasmas has seen a sustained rapid growth in recent years. This can be attributed to the remarkablediscovery of new states of (soft) matter - the liquid and crystalline plasmas - in 1994. Following this discovery, many researchers throughout theworld decided to explore and investigate the new physics that was beckoning. Now the field produces about one scientific publication per day,many links to other disciplines are being forged (e g colloid physics solid state granular media environmental research etc) and application

potentials are under investigation, too (e.g. nanostructured materials, plasma cleaning devices, adaptive electrodes, particle manipulation andmodification, etc). The young field of complex (dusty) plasmas is beginning to come of age. This seemed like an excellent time to produce aFocus Issue on the topic. Through the diversity of the contributions the reader is able to get a synoptic view of the field which, of course, a reviewarticle cannot provide. The papers cover basic aspects of dust-plasma interactions in the laboratory, under microgravity conditions and in space, as

, Wwell as the application of plasma-processed micro-particles. The contributions focus on the latest scientific advances in complex plasmas. Judgingfrom the huge response to the announcement of the Focus Issue in New Journal of Physics, we, the editors, conclude that the field is still growingand that the timing for the Focus Issue is just right!We would like to express our appreciation to Alexander Bradshaw who initiated this Focus Issue. Finally, we wish to thank the editorial team,especially Tim Smith, the many referees and the contributors for their excellent work.
