Bose–Einstein condensation on an atom chip

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.

Bose-Einstein condensates on an atom chips

Atom chips are a reliable and versatile tool for the production and control of Bose-Einstein Condensates (BECs). They also offer the possibility of realising new, chip-based quantum devices. We have recently produced BECs on an atom chip fabricated with silver foil. Because of its high current capacity, our chip can produce moderately tight traps at distances further from the chip surface, avoiding losses and fragmentation of condensates seen on other experiments. We will also report on our progress towards efficient atom detection using a STIRAP based photoionisation scheme.
