Abstract

We investigate fast frictionless expansion for growing Bose-Einstein condensates described by the Gross-Pitaevskii gain equation. We show that fast frictionless expansion can be generalized to a condensate continuously replenished by pumping from the reservoir. We apply our formalism to the harmonically trapped condensate and an optical lattice.
