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 con...

The effects of surface-induced evaporative cooling on an atom chip
are investigated. The evolutions of temperature, number and
phase-space density of the atom cloud are measured when the atom
cloud is brought close to the surface. Rapid decrease of the
temperature and number of the atoms is found wh...
