Abstract:
We [1] show that the standard Landau and
Bogoliubov superfluidity criteria fail in low-
dimensional circuits. Proper determination of
the superfluidity regime-diagram must
account for the crucial role of chaos, an
ingredient missing from the conventional
stability analysis. Accordingly, we find novel
types of superfluidity, associated with
irregular or chaotic or breathing vortex
states.
