The research group of Ewan Wright has recently found applications in the simulation of a variety of physical phenomena such as superfluidity, vortex instabilities, and artificial gauge theories. This research presents the new opportunity for a room-temperature photon superfluid which can mimic the geometry of a rotating acoustic black hole. This allows the researchers to measure the local flow velocity and speed of waves in the photo superfluid. Read more.
