Revisiting Thomson's model with multiply charged superfluid helium nanodroplets
Ernesto Garcia-Alfonso, Francesco Ancilotto, Manuel Barranco +3
We study superfluid helium droplets multiply charged with ions. When stable, the charges are found to reside in equilibrium close to the droplet surface, thus representing a physic…
Self-sustained deformable rotating liquid He cylinders: The pure normal fluid He and superfluid He cases
Martí Pi, Francesco Ancilotto, Manuel Barranco +2
We have studied self-sustained, deformable, rotating liquid He cylinders of infinite length. In the normal fluid He case, we have employed a classical model where only surface…
Merging of superfluid Helium nanodroplets with vortices
J. M. Escartin, F. Ancilotto, M. Barranco +1
Within Density Functional Theory, we have investigated the coalescence dynamics of two superfluid helium nanodroplets hosting vortex lines in different relative orientations, which…

M. Pi, J. M. Escartin, F. Ancilotto +1
Within Density Functional Theory, we have studied the interplay between vortex arrays and capillary waves in spinning prolate He-4 droplets made of several thousands of helium atom…
Vorticity and quantum turbulence in the merging of superfluid Helium nanodroplets
José María Escartín, Francesco Ancilotto, Manuel Barranco +1
We have studied the merging of two He droplets at zero temperature, caused by their Van der Waals mutual attraction. During the early stages of the merging, density structures…

Francesc Malet, Martí Pi, Manuel Barranco +2
We have investigated the dipole charge- and spin-density response of few-electron two-dimensional concentric nanorings as a function of the intensity of a perpendicularly applied m…
