摘要: A one-dimensional model of interacting electrons with on-site U, nearest-neighbor V, and correlated-hopping interaction T* is studied at half filling using the continuum-limit field theory approach. The ground-state phase diagram is obtained for a wide range of coupling constants. In addition to the insulating spin-and charge-density wave phases for large U and V, respectively, we identify bond-located ordered phases corresponding to an enhanced Peierls instability in the system for T*> 0,| U− 2 V|< 8 T*/π and to a staggered magnetization …
