Can a gravitating superfluid liquid rotate?

The question in the title of this paper is answered unambiguously. The rotation of an external object would, by entraining the condensate along with the inertial frame of reference, lead to the formation of a meniscus (the velocity v3s is not zero). This rotation of the condensate, however, would not generate Lense-Thirring forces and would not contribute to the angular momentum of the system (the velocity ui3 is zero). In this sense, the condensate, like superfluid 4He at a small angular velocity, cannot rotate. © 1995 American Institute of Physics.
