From harmonic to sound-like oscillations in a quantum gas confined in a gravity compensated shell trap
Matthieu Cassus, Rishabh Sharma, Maxime Pesche +4
We study the center of mass oscillations of a quantum gas in a shell shaped trap in the presence of a vertical force opposed to gravity. The measured harmonic frequency at the bott…
Thermal melting of a vortex lattice in a quasi two-dimensional Bose gas
Rishabh Sharma, David Rey, Laurent Longchambon +3
We report the observation of the melting of a vortex lattice in a fast rotating quasi-two dimensional Bose gas, under the influence of thermal fluctuations. We image the vortex lat…
Loading a quantum gas from a hybrid dimple trap to a shell trap
David Rey, Simon Thomas, Rishabh Sharma +4
Starting from a degenerate Bose gas in a hybrid trap combining a magnetic quadrupole trap and an attractive optical trap resulting from a focused laser beam, we demonstrate the eff…
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…
A versatile ring trap for quantum gases
Mathieu de Goër de Herve, Yanliang Guo, Camilla de Rossi +5
We report on the confinement of a Bose-Einstein condensate in an annular trap with widely tunable parameters. The trap relies on a combination of magnetic, optical and radio-freque…
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…
