Full-CI Quantum Chemistry using the Density-Matrix Renormalization Group

S. Daul, I. Ciofini, C. Daul +1

We describe how density-matrix renormalization group (DMRG) can be used to solve the full-CI problem in quantum chemistry. As an illustration of the potential of this method, we ap…

Frustrated Hubbard ladders and superconductivity in -BEDT-TTF organic compounds

S. Daul, D. J. Scalapino

Half-filled two-leg Hubbard ladders have spin-gapped short-range antiferromagnetic correlations while three-leg ladders have power law antoferromagnetic correlations, and both syst…

First and second order ferromagnetic transition at T=0 in a 1D itinerant system

S. Daul

We consider a modified version of the one-dimensional Hubbard model, the t1-t2 Hubbard chain, which includes an additional next-nearest-neighbor hopping. It has been shown that at…

Effect of the W-term for a t-U-W Hubbard ladder

S. Daul, D. J. Scalapino, Steven R. White

Antiferromagnetic and d_{x2-y2}-pairing correlations appear delicately balanced in the 2D Hubbard model. Whether doping can tip the balance to pairing is unclear and models with ad…

Phase diagram of the half-filled Hubbard chain with next-nearest-neighbor hopping

S. Daul, R. M. Noack

We investigate the ground-state phase diagram of the half-filled one-dimensional Hubbard model with next-nearest-neighbor hopping using the Density-Matrix Renormalization Group tec…
