Название: Current Noise and Long Time Tails in Biased Disordered Random Walks
Авторы: Lehr W., Machta J.
Аннотация:
We calculate the mean velocity and the velocity correlation function for a random walk with a uniform bias on a disordered chain. We find a new long time tail in the velocity correlation function due to the combined effects of the bias and of the disorder in the site variables.
