The critical threshold conjecture for Bargmann-Fock percolation

Let Dp\mathcal{D}_p denote the excursion domain at level pp associated with a centered, normalized, non-degenerate, sufficiently smooth, stationary, isotropic, and positively correlated random field on R2\mathbb{R}^2 with sufficient correlation decay. Critical threshold conjecture. The probability that Dp\mathcal{D}_p has an unbounded connected component is 11 if p>0p>0, and 00 otherwise. This conjecture predicts that the self-dual level p=0p=0 is the critical threshold for planar Gaussian percolation, analogously to the critical parameter p=1/2p=1/2 in planar Bernoulli percolation. The cited context does not indicate that the conjecture has been resolved.
