Perturbation theory for bright spinor Bose--Einstein condensate solitons
Evgeny V. Doktorov, Jiandong Wang, Jianke Yang
We develop a perturbation theory for bright solitons of the F=1 integrable spinor Bose-Einstein condensate (BEC) model. The formalism is based on using the Riemann-Hilbert problem…
Modulational instability and nonlocality management in coupled NLS system
Evgeny V. Doktorov, Maxim A. Molchan
The modulational instability of two interacting waves in a nonlocal Kerr-type medium is considered analytically and numerically. For a generic choice of wave amplitudes, we give a…
Modulational instability in nonlocal Kerr-type media with random parameters
E. V. Doktorov, M. A. Molchan
Modulational instability of continuous waves in nonlocal focusing and defocusing Kerr media with stochastically varying diffraction (dispersion) and nonlinearity coefficients is st…
Full-time dynamics of modulational instability in spinor Bose-Einstein condensates
Evgeny V. Doktorov, Vassilis M. Rothos, Yuri S. Kivshar
We describe the full-time dynamics of modulational instability in F=1 spinor Bose-Einstein condensates for the case of the integrable three-component model associated with the matr…
Dynamics of subpicosecond dispersion-managed soliton in a fibre: A perturbative analysis
Evgeny V. Doktorov
A model is studied which describes a propagation of a subpicosecond optical pulse in dispersion-managed fibre links. In the limit of weak chromatic dispersion management, the model…
Perturbation-induced radiation by the Ablowitz-Ladik soliton
E. V. Doktorov, N. P. Matsuka, V. M. Rothos
An efficient formalism is elaborated to analytically describe dynamics of the Ablowitz-Ladik soliton in the presence of perturbations. This formalism is based on using the Riemann-…
