Power laws in a 2-leg ladder of interacting spinless fermions
L. G. Caron, C. Bourbonnais
We use the Density-Matrix Renormalization Group to study the single-particle and two-particle correlation functions of spinless fermions in the ground state of a quarter-filled lad…
Comment on "Absence of a Slater Transition in the Two-Dimensional Hubbard Model"
B. Kyung, J. S. Landry, D. Poulin +1
In a recent paper, Phys. Rev. Lett. 87, 167010/1-4 (2001), Moukouri and Jarrell presented evidence that in the two-dimensional (d=2) Hubbard model at half-filling there is a metal-…
On superconductivity in armchair carbon nanotubes
A. Sédéki, L. G. Caron, C. Bourbonnais
We use the momentum space renormalization group to study the influence of phonons and the Coulomb interaction on the superconducting response function of armchair single-walled nan…
(Sr/Ca)_{14}Cu_{24}O_{41} spin ladders studied by NMR under pressure
Y. Piskunov, D. Jérome, P. Auban-Senzier +5
(63)Cu-NMR measurements have been performed on two-leg hole-doped spin ladders Sr_{14-x}Ca_{x}Cu_{24}O_{41} single crystals (0-x-12) at several pressures up to the pressure domain…
Conserving approximations vs Two-Particle Self-Consistent Approach
S. Allen, A. -M. S. Tremblay, Y. M. Vilk
The conserving approximation scheme to many-body problems was developed by Kadanoff and Baym using the functional-derivative approach. Another approach for the Hubbard model also s…
Influence of oxygen isotope exchange on the ground state of manganites
V. N. Smolyaninova, Amlan Biswas, P. Fournier +4
We report a study of oxygen isotope effects on low temperature specific heat, magnetization, and resistivity of LaCaMnO and (LaPrCa$_{0.33…
Short-range spin correlations and pseudogap in underdoped cuprates
Bumsoo Kyung
In this paper we show that local spin-singlet amplitude with d-wave symmetry can be induced by short-range spin correlations even in the absence of pairing interactions. In the pre…
Interplay between spin-density-wave and superconducting states in quasi-one-dimensional conductors
Raphael Duprat, C. Bourbonnais
The interference between spin-density-wave and superconducting instabilities in quasi-one-dimensional correlated metals is analyzed using the renormalization group method. At the o…
Induced local spin-singlet amplitude and pseudogap in high cuprates
Bumsoo Kyung
In this paper we show that local spin-singlet amplitude with d-wave symmetry, , can be induced by short-range spin correlations even in the absence of pairing int…
