Tuning the Critical Current in Toroidal Superfluids via Controllable Impurities
K. Xhani, G. Del Pace, N. Grani +4
We combine numerical and experimental approaches to study how impurities affect the maximum superflow in an annular Bose-Einstein condensate. By tuning the impurity density, we ach…

Self-induced Josephson oscillations and self-trapping in a supersolid dipolar quantum gas
Beatrice Donelli, Nicolò Antolini, Giulio Biagioni +8
The Josephson effect characterizes superfluids and superconductors separated by a weak link, the so-called Josephson junction. A recent experiment has shown that Josephson oscillat…
