论文摘要
混合$^3 $ He-$^4 $ He He液滴是由低温流体射流的流体动力不稳定产生的，可能会在通过实验设备的喷嘴中获得角动量。这些独立的液滴冷却至非常低的同位素隔离，从而产生了一个几乎纯净的$^3 $，他的外壳围绕着非常$^4 $ He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He-He的富裕良好，核心富裕又非常少。在这里，使用密度功能理论研究了旋转混合氦液滴的稳定性和外观，用于同位素组成，突出显示的同位素组成，其中一些明显的例外与超流体内核的存在有关，类似于粘性旋转液滴的类比。
Mixed $^3$He-$^4$He droplets created by hydrodynamic instability of a cryogenic fluid-jet may acquire angular momentum during their passage through the nozzle of the experimental apparatus. These free-standing droplets cool down to very low temperatures undergoing isotopic segregation, developing a nearly pure $^3$He crust surrounding a very $^4$He-rich superfluid core. Here, the stability and appearance of rotating mixed helium droplets are investigated using Density Functional Theory for an isotopic composition that highlights, with some marked exceptions related to the existence of the superfluid inner core, the analogies with viscous rotating droplets.
