Expansion of a quantum gas in a shell trap
Yanliang Guo, Emmanuel Mercado Gutierrez, David Rey +6
We report the observation of the controlled expansion of a two-dimensional quantum gas confined onto a curved shell-shaped surface. We start from the ellipsoidal geometry of a dres…
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…
Comparison of time profiles for the magnetic transport of cold atoms
Thomas Badr, Dany Ben Ali, Joseph Seaward +5
We have compared different time profiles for the trajectory of the centre of a quadrupole magnetic trap designed for the transport of cold sodium atoms. Our experimental observatio…
Local correlations reveal the superfluid to normal boundary in a trapped two-dimensional quantum gas
Romain Dubessy, Camilla De Rossi, Mathieu De Goër de Herve +4
This paper reports the model free determination of the two-fluid dynamics in a trapped two-dimensional Bose gas, relying on a local principal component analysis of the dynamics aft…
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…
A two-dimensional quantum gas in a magnetic trap
Karina Merloti, Romain Dubessy, Laurent Longchambon +4
We present the first experimental realization of a two-dimensional quantum gas in a purely magnetic trap dressed by a radio frequency field in the presence of gravity. The resultin…
