Supersonic rotation of a superfluid: a long-lived dynamical ring
Yanliang Guo, Romain Dubessy, Mathieu de Goër de Herve +5
We present the experimental realization of a long-lived superfluid flow of a quantum gas rotating in an anharmonic potential, sustained by its own angular momentum. The gas is set…

Probing superfluidity in a quasi two-dimensional Bose gas through its local dynamics
Camilla De Rossi, Romain Dubessy, Karina Merloti +5
We report direct evidence of superfluidity in a quasi two-dimensional Bose gas by observing its dynamical response to a collective excitation. Relying on a novel local correlation…
