Soliton motion in the case of a nonzero reflection coefficient Martínez Alonso, Luis ©1985 The American Physical Society. The author wishes to thank G. Garcia Alcaine for helpful conversations. Partial financial support by Comision Asesora de Investigacion Cientifica y Tecnica is gratefully acknowledged. A method is given for finding the shifts in position of the solitons for the case of nonzero reflection coefficient. Expressions for boost generators in terms of scattering data play a prominent role in the analysis. Phase-shift formulas which show the effect of the radiation component on the soliton motion are deduced for the nonlinear Schrodinger equation, the Korteweg —de Vries equation, and the sine-Gordon equation. 2023-06-21T02:09:47Z 2023-06-21T02:09:47Z 1985 journal article 0031-9007 10.1103/PhysRevLett.54.499 https://hdl.handle.net/20.500.14352/65009 http://dx.doi.org/10.1103/PhysRevLett.54.499 http://journals.aps.org eng open access American Physical Society
