The lowest man-made temp achieved is 3 nanoKelvin above absolute zero, the coldest temp theoretically possible. It was reached using rarified gas composed of atoms of 85 rubidium which form a Bose-Einstein condensate where the atoms behave a one superatom. It was achieved by scientists at the University of Colorado USA, with association of the National Institue of Technology in Boulder Colorado, USA.

Update report! I just found a newer Guinness Book of Records site which states that:
On Sept 12 2003 scientists at the MIT in Cambridge Mass. achieved a temp of 450 picokelvin which beats the previous record by a factor of six.
