Abstract

If one rotates a metal disk coated with a thin adsorbed film of superfluid helium, does the helium move with the disk or does it remain at rest? This is the intriguing question to which Vittoratos and Meincke of Toronto University have recently been addressing themselves and, in contrast with earlier workers, they seem to have been successful in establishing at least part of the answer (Phys. Rev. Lett. 34, 796; 1975).
