✦ Synopsis

We use the time-dependent mean-field Gross-Pitaevskii
equation to study the formation of a dynamically-stabilized
dissipation-managed bright soliton in a quasi-one-dimensional
Bose-Einstein condensate (BEC). Because of three-body
recombination of bosonic atoms to molecules, atoms are lost
(dissipated) from a BEC. Such dissipation leads to the decay of a
BEC soliton. We demonstrate by a perturbation procedure that an
alimentation of atoms from an external source to the BEC may
compensate for the dissipation loss and lead to a
dynamically-stabilized soliton. The result of the analytical
perturbation method is in excellent agreement with mean-field
numerics. It seems possible to obtain such a
dynamically-stabilized BEC soliton without dissipation in
laboratory.
