We present an analysis of ion temperatures in laser-produced plasmas formed from solids with different initial lattice structures. We show that the equilibrium ion temperature is limited by a mismatch between the initial crystallographic configuration and the close-packed configuration of a strongly-coupled plasma, similar to experiments in ultracold neutral plasmas. We propose experiments to demonstrate and exploit this crystallographic heating in order to produce a strongly coupled plasma with a coupling parameter of several hundred.
我们对由具有不同初始晶格结构的固体形成的激光产生等离子体中的离子温度进行了分析。我们表明，平衡离子温度受到初始晶体结构与强耦合等离子体的密堆积结构之间不匹配的限制，这与超冷中性等离子体中的实验类似。我们提出了实验来证明和利用这种晶体加热，以产生耦合参数为几百的强耦合等离子体。
