摘要：
The single-hole dynamics in a coupled-chain model described by the t-t'-J model is studied. The excitation spectrum is obtained exactly and analytically and shows a structure consisting of bound, antibound and extended states. Based on the exact results obtained, the possibility of a localization-to-delocalization transition for the hole is conjectured.
