Spin-gap fixed points in the double-chain problem

Published Jul 1, 1994• 95 citations

Abstract

Applying the bosonization procedure to weakly coupled Hubbard chains, we discuss the fixed points of the renormalization-group procedure where all spin excitations are gapful and a singlet pairing becomes the dominant instability.

Singlet pairing in the double-chaint-Jmodel

Dmitri V. Khveshchenko

Applying the bosonization procedure to constrained fermions in the framework of the one-dimensional t-J model, we discuss a scenario of singlet superconductivity in a lightly doped double chain where all spin excitations remain gapful.

Phase diagram of the two-chain Hubbard model

Young‐Ho Park, Shoudan Liang, T. K. Lee

We have calculated the charge gap and spin gap for the two-chain Hubbard model as a function of the on-site Coulomb interaction and the interchain hopping amplitude. We used the density matrix renormalization group method and developed a method to calculate separately the gaps numerically for the symmetric and antisymmetric modes with respect to the exchange of the chain indices. We have found very different behaviors for the weak and strong interaction cases. Our calculated phase diagram is compared to the one obtained by Balents and Fisher using the weak coupling renormalization group technique.

Correlation functions in the three-chain Hubbard ladder

T. Kimura, Kazuhiko Kuroki, Hideo Aoki

In order to check whether odd-numbered Tomonaga-Luttinger ladders are dominated by antiferromagnetic correlations associated with gapless spin excitations, correlation functions of the doped three-chain Hubbard model are obtained with the bosonization at the renormalization-group fixed point. The correlation of the singlet superconducting pairing across the central and edge chains is found to be dominant, reflecting two gapful spin modes, while the intraedge spin-density-wave correlation, reflecting the gapless mode, is only subdominant. This implies that, when there are multiple spin modes, a dominant superconductivity can arise from the presence of some spin gap(s) despite the coexistence of power-law correlated spins.

Bosonization analysis of the antiferromagnetic s= 12 spin ladders

D. Schmeltzer

We apply the bosonization method to study three coupled antiferromagnetic Heisenberg chains. Using free boundary conditions we show within renormalization-group theory that the low-energy excitations are gapless.

Weak-coupling approach to hole-dopedS=1 Haldane systems

Satoshi Fujimoto, Norio Kawakami

As a weak-coupling analogue of hole-doped S=1 Haldane systems, we study two models for coupled chains via Hund coupling; coupled Hubbard chains, and a Hubbard chain coupled with an S=1/2 Heisenberg chain. The fixed point properties of these models are investigated by using bosonization and renormalization group methods. The effect of randomness on these fixed points is also studied. It is found that the presence of the disorder parameter inherent in the Haldane state in the former model suppresses the Anderson localization for weak randomness, and stabilizes the Tomonaga-Luttinger liquid state with the spin gap.
