Rydberg states with a liquid core
Juan Carlos Acosta Matos, P. Giannakeas, Jan M. Rost
We develop a self-consistent approach that provides an explicit potential for a Rydberg electron whose ionic core consists of a polarizable medium, typically realized with superflu…

Transitional supersolidity in ion doped helium droplets
Juan Carlos Acosta Matos, Panos Giannakeas, Matteo Ciardi +2
He nanodroplets doped with an alkali ion feature a snowball of crystallized layers surrounded by superfluid helium. For large droplets, we predict that a transitional supersoli…
