RT Journal Article T1 Soliton-radiation interaction in nonlinear integrable lattices A1 Martínez Alonso, Luis AB The effect of the radiation modes on soliton motion in nonlinear lattices is investigated. A method based on the inverse scattering transform is developed, which enables us to characterize the position shifts of solitons due to their interaction with the radiation component.

In particular, it holds for the Toda lattice. 10. N. Theodorakopoulos and F. G. Mertens, Phys. Rev. B 28, 3512 (1983). 11. This equation is obtained by setting z =k^1 in Eq. (2.5) of Ref. 7, p. 52.
