GLASSY TRAPPING OF MANIFOLDS IN NONPOTENTIAL RANDOM FLOWS

We study the dynamics of polymers and elastic manifolds in nonpotentia l static random flows. Barriers are found to be generated from combine d effects of elasticity, disorder, and thermal fluctuations. This lead s to glassy trapping even in pure barrier-free divergenceless flows, w ith anomalously small response to an applied force. We find a new reno rmalization-group fixed point at finite temperature and compute the ro ughness, dynamical, and response exponents for directed and isotropic manifolds.
