From what you're describing sounds like a bose-einstein condensate. What happens basically ( Look at
this site ) is that when atoms reach absolute zero they condense into a single mass, effictively what is nicknamed a ' super atom '. They have
been able to do this by slowing the atoms down ( thereby reducing the temperature ) using lasers. They got the temperature down to within a few
billionths of a degree when the bose-einstein condensate was formed.
