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…
Universal shock-wave propagation in one-dimensional Bose fluids
Romain Dubessy, Juan Polo, Hélène Perrin +2
We propose a protocol for creating moving, robust dispersive shock waves in interacting one-dimensional Bose fluids. The fluid is prepared in a moving state by phase imprinting and…
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…
Oscillations and decay of superfluid currents in a one-dimensional Bose gas on a ring
Juan Polo, Romain Dubessy, Paolo Pedri +2
We study the time evolution of a supercurrent imprinted on a one-dimensional ring of interacting bosons in the presence of a defect created by a localized barrier. Depending on int…
