In the present work we extend the concept of coherent shift for the extendedBose-Hubbard model and Fermi-Hubbard model. We present two types of local boundpair (BP) for Bose system and one type for Fermi system. It is shown exactlythat the perfect coherent shift can be achieved in such models. We find thatfor a Bose on-site BP, the perfect coherent shift condition depends on thenearest-neighbor interaction strength and the momentum of the incident singleparticle wavepacket, while for the other two types of BPs, it is independent ofthe initial state in the proposed systems.
