Absolute zero is theoretical, and it simply means the atoms have stopped moving entirely. I've heard of a theory of less than absolute zero, but I don't know how you can stop motion more than completely.
There was a cool documentary called the Quest for Cold that showed the history of cold and the quest for near absolute zero and the neat property of matter at those temperatures.
