In this paper, we study dimension reduction of the three-dimensional (3D) Gross–Pitaevskii equation (GPE) modeling Bose–Einstein condensation under different limiting interaction and trapping frequency parameter regimes. Convergence rates for the dimension reduction of 3D ground state and dynamics of the GPE in the case of disk-shaped condensation and… (More)
Soliton trapping is demonstrated in an all-fiber Tm fiber laser. The central wavelength shift between the two orthogonal polarized components of the vector soliton is determined by the cavity birefringence.
