AbstractThe one-dimensional antiferromagnetic correlated electron system described by the unusual t–U–J model with alternating on-site interactions at odd ($$U_o$$ U o ) and even ($$U_e$$ U e ) sites is studied analytically. At weak coupling, the use of bosonization and renormalization-group techniques helps to obtain ground-state phase diagram. At quarter filling, the unequal on-site repulsion ($$U_e\ne U_o$$ U e ≠ U o ) causes the occurrence of umklapp processes and the generation of a charge excitation gap. Contrary to the usual case ($$U_e=U_o$$ U e = U o ), the system is not metallic but insulating. For $$U_e+U_o<2J$$ U e + U o < 2 J , the system is in a spin-gapped phase with charge-density-wave (CDW) instability; for $$U_e+U_o\ge 2J$$ U e + U o ≥ 2 J , the system is in a spin-gapless phase characterized by the coexistence of both CDW and spin-density-wave (SDW) instabilities, where the SDW correlation dominates over the CDW one.
