[Daniel Oi]

There will be an extra John Anderson colloquium by our SUPA Distinguished Visitor, Prof David Snoke (Pittsburgh) on Wednesday 1st July. As usual tea/coffee will be served after the talk.

Speaker: Prof David Snoke, Department of Physics and Astronomy, University of Pittsburgh.
Venue: John Anderson JA3.14
Times/Date: 3pm Wednesday 1st July 2015

Title: Superfluids of Light

Abstract:
It is possible to engineer the properties of photons in an optical medium to have an effective mass and repulsive interactions, so that they act like a gas of atoms. These "renormalized photons" are called polaritons. In the past ten years, several experiments have demonstrated many of the canonical effects of Bose-Einstein condensation and superfluidity of polaritons. In this talk I will review some of this past work and present recent results which show quantized circulation of the polariton condensate in a ring trap.
