![]() Period of a soliton in a harmonic trap increases as one moves from Furthermore, the periodic dynamics ofĭark solitons in a harmonic trap sco ren and two solitonsĬollision sco1 were studied by numerically solving the ![]() Solutions corresponding to grey solitons was alsoĬonsidered spu sco1. Properties of black solitons in the BCS-BEC crossover wereĭemonstrated ant by the real solutions of the Bogoliubov-de Instability with collapsing into vortex rings, which propagate in soliton-like mannerīased on the BCS mean-field theory pdg, the existence and Therefore, instead of a very slow oscillation as observedĮxperimentally, we find that the created dark soliton undergoes a transverse snake The stability criterion is not fulfilled by the parameters of the recentĮxperiment. Transverse confinements in the unitarity limit, we not only give the criterion of dynamical stability,īut also find that the soliton and a hybrid of solitons and vortex rings can be characterizedīy different oscillation period. By studying the stability of initially off-center dark solitons under various tight We calculate the periods of dark solitons oscillating in a trap, andįind a good agreement with the results based on the Bogoliubov-de GennesĮquations. ![]() ![]() Numbers and trap aspect ratios within the framework of the order-parameter equation. Of dark solitons in anisotropic Fermi gases for a range of particle We present an investigation of generation, dynamics and stability ![]()
