Non-Gaussian features of chaotic Hamiltonian transport
arXiv:0711.4539 · doi:10.1088/1742-5468/2008/01/P01005
Abstract
Some non-Gaussian aspects of chaotic transport are investigated for a general class of two-dimensional area-preserving maps. Kurtosis, in particular, is calculated from the diffusion and the Burnett coefficients, which are obtained analytically. A characteristic time scale delimiting the onset of the Markovian regime for the master equation is established. Some explicit examples are discussed.
