Transfer of information in noise induced transport

Time correlated fluctuations interacting with a spatial asymmetry potential are sufficient conditions to give rise to transport of Brownian particles. The transfer of information coming from the nonequilibrium bath, viewed as a source of negentropy, give rise to the correlated noise. The algorithmic complexity of an object provides a means of quantifying its information co ntents. The Kolmogorov information entropy or algorithmic complexity is inv estigated in order to quantify the transfer of information that occurs in c omputational models showing noise induced transport. The complexity is meas ured in terms of the average number of bits per time unit necessary to spec ify the sequence generated by the system. (C) 1999 Elsevier Science B.V. Al l rights reserved.
