How is flying possible in a superfluid? Probing lift generation in liquid helium-4 to identify its Newtonian features (LL2326)

Superfluid helium-4 is a unique cryogenic liquid and its similarities with classical Newtonian fluids have yet to be neatly identified. In view of addressing this open question, we will investigate in unprecedented detail a canonica...
