We examine and extend recent results for the statistics of a gaussian polymer chain of length t in a quenched random potential μ (r). This problem can be mapped onto one involving the nonlinear evolution equation h (r, t) = ∇2h + (∇h)2 - μ(r) for a growing interface in the presence of a time-independent, but spatially varying, random flux - μ (r). [The corresponding problem for a directed polymer, equivalent to a flux random in both time and space, was studied by M. Kardar, G. Parisi and Y.-C. Zhang, Phys. Rev. Lett. 56 (1986) 889.] A free chain in a true white-noise potential, in space dimensions d = 2, 3, is predicted to collapse to a linear size R ∼ v1 /(d - 4)[ln V] 1/(d - 4) where v is the mean-square potential fluctuation (presumed s...
