Cloud parameter estimation for interacting BEC after time-of-flight
Rasmus Malthe Fiil Andersen, Stine Frederiksen, Laurits Stokholm, Ilja Zebergs et autres
Experiments on Bose-Einstein condensates at finite temperature typically extract the system parameters, such as temperature, atom number, and condensed fraction from time-of-flight images taken after a free expansion time. This paper systematically examines the effect of repulsive interactions between the condensed and …
