Abstract
The dynamics of self-interacting quasiparticles in 1Dsystems with
long-range dispersive interactions isexpressed in terms of a
nonlocal nonlinear Schrödingerequation. Two branches of stationary
solutions are found.The new branch which contains a cusp soliton
is shown to beunstable and blowup is observed. Moving solitons
radiatewith a wavelength proportional to the velocity.
