AMPLIFICATION OF INTRINSIC FLUCTUATIONS BY CHAOTIC DYNAMICS IN PHYSICAL SYSTEMS

A quantitative method for the treatment of large-scale intrinsic fluctuations amplified by chaotic trajectories in macrovariable physical systems is presented. Paradigmatic results for the Rossler model and preliminary computational results for chaotic Josephson junctions and for chaotic multimode Nd:YAG (yttrium aluminum garnet) lasers are described. These studies are directed towards identification of a real physical system in which experimental confirmation may be realized. The probability distribution on the intrinsic-noise-modified, chaotic attractor is identified as a likely candidate for comparison of experiment and theory.
