Rotons and Quantum Evaporation from Superfluid 4He
F. Dalfovo, A. Fracchetti, A. Lastri +2
The probability of evaporation induced by and rotons at the surface of superfluid helium is calculated using time dependent density functional theory. We consider excit…

Density functional calculations for 4He droplets
M. Casas, F. Dalfovo, A. Lastri +2
A novel density functional, which accounts correctly for the equation of state, the static response function and the phonon-roton dispersion in bulk liquid helium, is used to predi…

Bounds for the phonon-roton dispersion in superfluid 4He
J. Boronat, J. Casulleras, F. Dalfovo +2
The sum rule approach is used to derive upper bounds for the dispersion law of the elementary excitations of a Bose superfluid. Bounds are explicitly calculated for the ph…
