Query: Anomalous buoyancy of quantum bubbles in immiscible Bose mixtures   Buoyancy is a well-known effect in immiscible binary Bose-Einstein
condensates. Depending on the differential confinement experienced by the two
components, a bubble of one component sitting at the center of the other
eventually floats to the surface, around which it spreads either totally or
partially. We discuss how quantum fluctuations may significantly change the
volume and position of immiscible bubbles. We consider the particular case of
two miscible components, forming a pseudo-scalar bubble condensate with
enhanced quantum fluctuations (quantum bubble), immersed in a bath provided by
a third component, with which they are immiscible. We show that in such a
peculiar effective binary mixture, quantum fluctuations change the equilibrium
of pressures that define the bubble volume and modify as well the criterion for
buoyancy. Once buoyancy sets in, in contrast to the mean-field case, quantum
fluctuations may place the bubble at an intermediate position between the
center and the surface. At the surface, the quantum bubble may transition into
a floating self-bound droplet.
