Manifestations of local supersolidity of \(^{4}\bf {He}\) around a charged molecular impurity
- A frozen, solid helium core, dubbed a 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 \(^{4}\bf {He}\) atoms are indeed strongly localized akin to snowballs but still participate in vivid bosonic exchange induced by the rovibrational motion of the impurity. Such a combination of solidlike order with pronounced superfluid response in the first helium shell indicates that manifestations of local supersolid behavior of \(^{4}\bf {He}\) can be induced by charged molecules.
