Unequal on-site interaction effects in the one-dimensional electron system at quarter filling
Abstract The 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 tech...
