    "abstract": "We present the first experimental observation of modulation instability of\npartially spatially incoherent light beams in non-instantaneous nonlinear\nmedia. We show that even in such a nonlinear partially coherent system (of\nweakly-correlated particles) patterns can form spontaneously. Incoherent MI\noccurs above a specific threshold that depends on the beams\u0027 coherence\nproperties (correlation distance), and leads to a periodic train of\none-dimensional (1D) filaments. At a higher value of nonlinearity, incoherent\nMI displays a two-dimensional (2D) instability and leads to self-ordered arrays\nof light spots.",
