Effects of dimerization and interchain one-particle hopping in a weakly coupled dimerized chain system at quarter filling

Abstract

Effects of the intrachain dimerization and the interchain one-particle hopping, $t_b$, in a quasi-one-dimensional dimerized chain system at quarter filling have been studied, based on the perturbative renormalization group (PRG) approach. Based on the results, we discuss difference in the low-energy properties between TMTTF and TMTSF compounds.
