Condensed matter and materials physics}, month = {Nov}, note = {We study the interplay of randomness, electron correlation, and dimensionality effects in weakly coupled half-filled Hubbard chains with weak quenched random potentials, based on the renormalization-group (RG) approach. We perform a two-loop RG analysis of an effective action derived by using the replica trick, and examine the following crossovers and phase transitions from an incoherent metal regime: (1) a crossover to the Anderson localization regime, (2) an antiferromagnetic phase transition, and (3) a crossover to the quasi-one-dimensional weak-localization regime. The case of d=1+ε (ε≪1) dimensions is also mentioned.}, pages = {13323--13337}, title = {Interplay of randomness, electron correlation, and dimensionality effects in quasi-one-dimensional conductors}, volume = {62}, year = {2000}, yomi = {キシネ, ジュンイチロウ} }
