“Is This Even a Plasma?  Physics of Strongly Coupled Plasmas” by Scott Baalrud, Ph.D., Assistant Professor, Department of Physics & Astronomy, The University of Iowa

Abstract:  Strongly coupled plasmas are dense, cold or highly charged systems in which the average Coulomb potential energy between constituent electrons and ions exceeds their average kinetic energy. Whereas traditional weakly coupled plasmas behave as ionized gases, strongly coupled plasmas behave as ionized liquids or solids. They play a key role in natural phenomena such as dense astrophysical objects, and laboratory experiments including dusty plasmas, ultra cold plasmas, and in inertial confinement fusion energy research. This talk will give an overview of how transport properties of strongly coupled plasmas fundamentally differ from weakly coupled plasmas in ways similar to how liquids differ from gases. It will also discuss recent advances in transport theory.
