A refined empirical stability criterion for nonlinear Schroedinger solitons under spatiotemporal forcing

Franz G. Mertens, Niurka R. Quintero, I. V. Barashenkov +1

We investigate the dynamics of travelling oscillating solitons of the cubic NLS equation under an external spatiotemporal forcing of the form $f(x,t)=a\exp [iK(t)x]$. For the cas…
