摘要：

We study analytically and numerically the depinning transition of a pinned charge density wave. We introduce a real space renormalization group approach with the method of decimation, which allows to determine the threshold both in the strong and weak pinning limit. We also perform a numerical renormalization of the system that allows to avoid the difficulties due to the large fluctuations in the weak pinning limit. The analytical results turn out to be in good agreement with the simulations.
