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…
Producing superfluid circulation states using phase imprinting
Avinash Kumar, Romain Dubessy, Thomas Badr +4
We propose a method to prepare states of given quantized circulation in annular Bose-Einstein condensates (BEC) confined in a ring trap using the method of phase imprinting without…
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…
