Application of the Feshbach-resonance management to a tightly confined Bose-Einstein condensate
Application of the Feshbach-resonance management to a tightly confined Bose-Einstein condensate
We study suppression of the collapse and stabilization of matter-wave solitons by means of time-periodic modulation of the effective nonlinearity, using the nonpolynomial Schroedinger equation (NPSE) for BEC trapped in a tight cigar-shaped potential. By means of systematic simulations, a stability region is identified in the plane of the modulation …
