Description:
Author(s): S. Lin, X. Z. Zhang, and Z. Song We study the dynamics of bound pairs in the extended Hubbard model driven by a linear external field. It is shown that two interacting bosons or singlet fermions with nonzero on-site and nearest-neighbor interaction strengths can always form bound pairs in the absence of an external field. There are... [Phys. Rev. A 90, 063411] Published Tue Dec 02, 2014
