Three-observable measurement of the critical velocity in a paraxial superfluid of light flowing past a mobile impurity
T. Aladjidi, M. Baker-Rasooli, T. D. Ferreira +4
We report the measurement of the critical velocity of a paraxial superfluid of light flowing past a mobile impurity, realized using a dual-wavelength optical scheme in a warm vapor…

Swimming against a superfluid flow: Self-propulsion via vortex-antivortex shedding in a quantum fluid of light
Myrann Baker-Rasooli, Tangui Aladjidi, Tiago D. Ferreira +4
A superfluid flows without friction below a critical velocity, exhibiting zero drag force on impurities. Above this threshold, superfluidity breaks down, and the internal energy is…
