Weak – coupling calculation of the gap structure of doped n – leg Hubbard ladders
Weak–coupling calculation of the gap structure of doped n–leg Hubbard ladders Abstract In weak coupling, the spin gap in doped, even, n–leg periodic Hubbard ladders reflects the energy to break a pair into separate quasiparticles. Here we investigate the structure of the gap within a spin–fluctuation exchange approximation. We also calculate the amplitude for removing a singlet pair from two la...
متن کاملHole doped Hubbard ladders
The formation of stripes in six-leg Hubbard ladders with cylindrical boundary conditions is investigated for two different hole dopings, where the amplitude of the hole density modulation is determined in the limits of vanishing DMRG truncation errors and infinitely long ladders. The results give strong evidence that stripes exist in the ground state of these systems for strong but not for weak...
متن کاملCorrelation functions in the three-chain Hubbard ladder.
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 b...
متن کاملThe Fermion-ladder Models: Extensions of the Hubbard Model with η-pairing
We propose the two-leg fermion-ladder models for SU(2|2) and SU(4) cases. The former is exactly the extended Hubbard model proposed by Essler, Korepin and Schoutens. The later is a new model also with η-pairing symmetry which is important for superconductivity. This new extension of the Hubbard model can be solved exactly. PACS: 75.10.Jm, 71.10.Fd, 05.30.Fk. Since the discovery of high-temperat...
