Complex Envelope Soliton in Bose-Einstein Condensate with Time Dependent Scattering Length
Ayan Khan, Rajneesh Atre, Prasanta K. Panigrahi
We elaborate on a general method to find complex envelope solitons in a cigar shaped Bose-Einstein condensate in a trap. The procedure incorporates time dependent scattering length…
