Vorticity and quantum turbulence in the merging of superfluid helium nanodroplets

JM Escartín, F Ancilotto, M Barranco, M Pi - Physical Review B, 2019 - APS
We have studied the merging of two identical He 4 droplets at zero temperature, caused by
their van der Waals mutual attraction. During the early stages of the merging, density …

Merging of superfluid helium nanodroplets with vortices
