This paper reports an experiment of creating Bose-Einstein
condensate (BEC) on an atom chip. The chip-based Z-wire current with
a homogeneous bias magnetic field creates a tight magnetic trap,
which allows for a fast production of BEC. After a 4.17-s forced
radio frequency evaporative cooling, a condensate with about 3000
atoms appears. The transition temperature is about 300~nK. This
compact system is quite robust, allowing for versatile extensions
and further studying of BEC. 相似文献
