An Approximation Method for the Scattering Data of One-Dimensional Soliton Equations under Arbitrary Rapidly Decreasing Initial Pulses

We present a novel approximation method that can predict the number of solitons asymptotically appearing under arbitrary rapidly decreasing initial wave packets. The number of solitons can be estim...

Collisions of Three-Component Vector Solitons in Bose-Einstein Condensates.

It is found that the solitonic properties in the quasi-one-dimensional system are quantitatively described by the integrable repulsive three-component Manakov model.

We investigate the stability and collision dynamics of dissipative matter-wave solitons formed in a quasi-one-dimensional Bose—Einstein condensate with linear gain and three-body recombination loss…

Waves and Solitons

In the previous chapter we considered the shape of steady state condensates, either homogeneous or confined by trapping potentials. We have seen that the condensate described by the GPE is a special…

We consider the linear stability of chiral matter-wave solitons described by a density-dependent gauge theory. By studying the associated Bogoliubov-de Gennes equations both numerically and…

Excitation Modes of Bright Matter-Wave Solitons.

It is shown that a deliberate mismatch of quench parameters allows for the excitation of breathing modes of the emerging soliton and for the determination of its breathing frequency as a function of atom number and confinement.

Non-integrable dynamics of matter-wave solitons in a density-dependent gauge theory

We study interactions between bright matter-wave solitons which acquire chiral transport dynamics due to an optically-induced density-dependent gauge potential. Through numerical simulations, we find…

Interaction forces among solitons in optical fibers.

It is shown here from the general two-soliton function that solitons in fibers exert forces on their neighbors that decrease exponentially with the distance between them and depend sinusoidally on their relative phase.

Experimental observation of interaction forces between solitons in optical fibers.

Pairs of soliton pulses are sent through a fiber, and the pulse separation at fiber input and output are compared, and close quantitative agreement with prediction is achieved, except when the pulses begin to merge.
