Physicists show that superfluid light is possible

(PhysOrg.com) -- Superfluidity – the phase of matter that enables a fluid to move up the sides of its container – has been known about since the 1930s. Since then, superfluidity has become a prime example of how quantum effects can become visible on the macroscopic scale under certain conditions. Although physicists have previously considered the possibility of superfluid light, their results have been inconclusive until now. In a new study, physicists from France have theoretically shown that superfluid motion of light is indeed possible, and have proposed an experiment to observe the phenomena.
