Yeah, but not through supercooled sodium. No need to find your reference as most of us are perfectly aware that the speed of light changes as it passes through various media.
In fact, even matter in the form of protons and neutrons can travel faster than light and does so all the time. It just so happens that the medium through which they travel is water and the source of the protons and neutrons is a fission reaction. The result can be seen as a beautiful blue light. I saw it when looking down through about 60 feet of water at a nuclear reactor under full power. There several such open reactors in the U.S. Three that I know of are the Advanced Test Reactor in Idaho, Ohio State University, and Texas A&M University.
