DOI: 10.1007/s10909-016-1690-x
Abstract: We study the head-on collision of a heliophilic xenon atom with a superfluid $$^4$$4He droplet made of 1000 atoms. At variance with the findings for a heliophobic cesium atom of a similar atomic weight, it… read more here.

DOI: 10.1063/5.0262866
Abstract: We review and discuss the underlying physics of critical velocities in flows of superfluid 4He (for historical reasons known as He II). Critical velocities, which indicate changes in the character of quantum three-dimensional flows, are… read more here.
