摘要：

We consider mesoscopic fluctuations of the Coulomb drag coefficient rho(D) in the system of two separated two-dimensional electron gases. It is shown that at low temperatures sample-to-sample fluctuations of rho(D) exceed its ensemble average. It means that in such a regime the sign of rho(D) is random and the temperature dependence almost saturates, rho(D) similar to 1/root T.
