Resonant incoherent excitation directly converts photons into excitons with vanishing center of mass momentum. The populated exciton state possesses long-range order, is very stable against perturbations, and should be observable via its unusual directional and density dependence in luminescence measurements.10 pages, 4 figuresMesoscale and Nanoscale PhysicsSuperconductivitytext
