The SU(2) BFSS matrix model describes two D0-branes, and its ground state is their bound state. Below is that state's joint density p(r, ρ) (Fig. 2), where r = x1, the largest singular value, measures the branes' separation at large r, and ρ = (x22 + x32)1/2 is the transverse radius. It is the state computed in the paper, whose ground-state overlap we rigorously showed to exceed 0.9999978.
