Cooling bosons by dimensional reduction
Yanliang Guo, Hepeng Yao, Sudipta Dhar +5
Cold atomic gases provide a remarkable testbed to study the physics of interacting many-body quantum systems. They have started to play a major role as quantum simulators, given th…
Experimental Observation of the 2D-1D Dimensional Crossover in Strongly Interacting Ultracold Bosons
Yanliang Guo, Hepeng Yao, Satwik Ramanjanappa +6
Dimensionality plays an essential role in determining the nature and properties of a physical system. For quantum systems the impact of interactions and fluctuations is enhanced in…
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…
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…
