Stable production of a strongly interacting Bose-Einstein condensate via mode matching

Author
Abstract
We describe a diabatic protocol to prepare a strongly interacting Bose-Einstein condensate in a regime where neither an adiabatic ramp nor a direct diabatic quench is desirable. This protocol is expected to achieve a nearly unit population transfer to the strongly interacting ground state for realistic experimental parameters for 85Rb. The protocol matches the initial and final density profiles by modifying the trap along with the scattering length during the quench. The protocol should reveal several properties of the strongly interacting Bose gas and enable further investigation of beyond-mean-field corrections to the Gross-Pitaevskii equation.
