论文摘要
通常在液体氦气中观察到阳离子的冷冻,固体氦芯,称为雪球。在这里,我们发现,使用路径积分模拟,围绕阳离子分子杂质,质子化甲烷,$^4 $ HE原子的原子确实是强烈的定位,类似于雪球,但仍会参与由杂质的RO振动运动引起的生动的骨气交换。这种类似固体顺序与明显的超氟反应在第一个氦壳中的组合表明,他可以通过带电的分子诱导 - 并通过实验探测他的局部超固体行为的表现。
A frozen, solid helium core, dubbed snowball, is typically observed around cations in liquid helium. Here we discover, using path integral simulations, that around a cationic molecular impurity, protonated methane, the $^4$He atoms are indeed strongly localized akin to snowballs but still participate in vivid bosonic exchange induced by the ro-vibrational motion of the impurity. Such combination of solid-like order with pronounced superfluid response in the first helium shell indicates that manifestations of local supersolid behavior of $^4$He can be induced -- and probed experimentally -- by charged molecules.
