Ultra-cold plasmas: a paradigm for stronglycoupled and classical electron fluids

摘要

Ultra-cold plasmas obtained by ionization of atomic Rydberg states arequalified as classical and strongly coupled electron fluids. They are shown to shareseveral common trends with ultra-cold electron flows used for ion-beam cooling.They exhibit specific stopping behaviour to charged particle beams, which may beused for diagnostic purposes. Ultra-cold plasmas are easily strongly magnetized.Then, one expects a strongly anisotropic behaviour of low ion velocity slowing downwhen the target electron cyclotron radius becomes smaller than the correspondingDebye length.
