Monte Carlo study of the pairing interaction in the two-leg Hubbard ladder
N. Bulut, T. Dahm, D. J. Scalapino
Monte Carlo calculations of the irreducible particle-particle interaction on a two-leg Hubbard ladder doped near half-filling are reported. As the temperature is lowered, this inte…
Enhanced d_{x^2-y^2} pairing correlations in the two-leg Hubbard ladder
R. M. Noack, N. Bulut, D. J. Scalapino +1
The two-leg Hubbard ladder is characterized by the ratio of the inter- to intra-leg hopping t_perp/t, the relative interaction strength U/t and the electron filling. Here, using de…
d_{x^2-y^2} Symmetry and the Pairing Mechanism
N. Bulut, D. J. Scalapino
An important question is if the gap in the high temperature cuprates has d_{x^2-y^2} symmetry, what does that tell us about the underlying interaction responsible for pairing. Here…
Determining the structure of the superconducting gap in Cu_{2}O_{3} 2-leg ladder materials
N. Bulut, D. J. Scalapino
Superconductivity has been recently observed in Sr_{0.4}Ca_{13.6}Cu_{24}O_{41.84} which contains quasi-one-dimensional Cu_{2}O_{3} 2-leg ladders. If, as suggested by some theories,…
Low-Energy Electronic Excitations of the Layered Cuprates and the Hubbard Model
N. Bulut
We present a review of the Quantum Monte Carlo results on the magnetic, charge and single-particle excitations as well as the pairing correlations of the two-dimensional Hubbard mo…
Short-Range Antiferromagnetic Correlations and the Photoemission Spectrum
N. Bulut
We present Quantum Monte Carlo results on the antiferromagnetic correlations and the one-electron excitations of the doped two-dimensional Hubbard model. These results are helpful…
