That sounds like this:
New Scientist, May 19, 2001
A practical way to make a time machine using two counter-circulating beams
of light is the goal of experiments by Ronald Mallett, professor of
theoretical physics at Connecticut University.
An ultra-cold bath of atoms known as a Bose-Einstein condensate is required
to slow down the speed of light to make it work, limiting the hypothetical
phenomenon to a lab curiosity for now.
