 The paper presents an effective and fast procedure for transferring a Bose-Einstein condensate from the ground state in a harmonic trap into the desired bands of an optical lattice using a designed pole sequence, which maximizes robustness and fidelity with respect to the target state. The method can be applied to two-dimensional or three-dimensional optical lattices where excited states are degenerate, and efficient shortcut methods have potential applications in quantum systems, quantum information processing, precise measurement, and investigating dynamics in excited bands.
