"Ultracold Neutral Plasmas"

Thomas Pattard , Dresden
[Host: Thomas Gallagher]
Recent advances in trapping and cooling of neutral atomic gases have permitted achieving ultralow temperatures far below 1K. With this, a wealth of new research fields has opened up, not at all limited to the realization of Bose Einstein condensation and related questions. In this talk, I will introduce one of these research topics, namely the physics of ultracold neutral plasmas. The fact that the plasma is many orders of magnitude colder than "conventional" plasmas leads to some remarkable properties, akin to conditions realized in exotic astrophysical environments. A theoretical description of these systems relies on methods and concepts bridging the gap between traditional atomic physics, plasma physics and nonequilibrium thermodynamics. On the other hand, this also means that the study of cold plasmas can provide new stimulus for all of these fields.
