Abstract
The static and dynamic force-force correlation function for the one-dimensional Toda lattice is calculated in the soliton-gas approximation. The dispersion and width of the soliton and phonon resonances are discussed in detail. Comparison with other calculations and molecular dynamics results shows that this approximation gives a reasonable description of most of the features in the correlations.Keywords
