Physicists are now starting to make a nearly perfect Bose gas in one dimension, a long-held
holy grail of quantum field theorists - ever since exact solutions were announced way back in the sixties.
Surprisingly, no exact correlation functions were ever found, even though this is the perfect signature
of the amazing transition that a Bose gas makes when it becomes Fermi-like in one dimension.
To cut a long story short - problem solved, with help from a multinational team in Australia, France
and Holland. I'll explain what the exact solutions are, how we got the correlations, how the different experiments work, and what is needed to test our predictions.
