    "abstract": "We present long-time simulations of expanding ultracold neutral plasmas,\nincluding a full treatment of the strongly coupled ion dynamics. Thereby, the\nrelaxation dynamics of the expanding laser-cooled plasma is studied, taking\ninto account elastic as well as inelastic collisions. It is demonstrated that,\ndepending on the initial conditions, the ionic component of the plasma may\nexhibit short-range order or even a superimposed long-range order resulting in\nconcentric ion shells. In contrast to ionic plasmas confined in traps, the\nshell structures are built up from the center of the plasma cloud rather than\nfrom the periphery.",
