Dark soliton formation in mode-locked lasers is investigated by means of a power-energy saturation model which incorporates gain and filtering saturated with energy, and loss saturated with power. It ...

Traveling Dark Solitons Superfluid Fermi Gases

Families of dark solitons exist in superfluid Fermi gases. The energy-velocity dispersion and
number of depleted particles completely determines the dynamics of dark solitons on a slowly-
varying ba...

We study soliton oscillations in a trapped superfluid Fermi gas across the Bose-Einstein conden-sate to Bardeen-Cooper-Schrieffer (BEC-BCS) crossover. We derive an exact equation relating the phase ju...
Development of instability of dark solitons generated by a flow of Bose-Einstein condensate past a concave corner

The stability of dark solitons generated by a supersonic flow of a Bose-Einstein condensate past a concave corner (or a wedge) is studied. It is shown that solitons in the dispersive shock wave genera...
Dynamics of ring dark solitons in Bose-Einstein condensates and nonlinear optics

2010/11/10
Quasiparticle approach to dynamics of dark solitons is applied to the case of ring solitons. It is shown that the energy conservation law provides the effective equations of motion of ring dark solito...

Motion of dark solitons trapped Bose-Einstein condensates

We use a multiple time scale boundary layer theory to derive the equation of motion for a
dark (or ‘grey’) soliton propagating through an effectively one-dimensional cloud of Bose-Einstein condensate...
