Polariton Superfluid Past an Obstacle

Interactive driven-dissipative Gross-Pitaevskii simulation of an exciton-polariton condensate in a semiconductor microcavity: a coherently pumped polariton fluid flows past a defect, showing the Landau-criterion transition from frictionless superfluid flow to a turbulent vortex wake.

This simulator numerically integrates the driven-dissipative Gross-Pitaevskii equation for an exciton-polariton condensate in a semiconductor microcavity — the same mean-field model used to interpret real polariton-fluid experiments. A coherently pumped polariton fluid streams at a tunable velocity past a localized defect, and the live 3D height field (density) and color (phase) reveal the Landau-criterion transition: below the local sound speed the flow is a frictionless superfluid with no wake, and above it a turbulent wake of quantized vortex-antivortex pairs nucleates downstream, tracked live as vortex-pair count, Mach number and Bogoliubov sound speed.
