Unequal on-site interaction effects in the one-dimensional electron system at quarter filling
The one-dimensional antiferromagnetic correlated electron system described by the unusual t–U–J model with alternating on-site interactions at odd ([Formula: see text] ) and even ([Formula: see text] ) sites is studied analytically. At weak coupling, the use of bosonization and renormalization-group...
