d-wave superconductivity in the hubbard model
The superconducting instabilities of the doped repulsive 2D Hubbard model are studied in the intermediate to strong coupling regime with the help of the dynamical cluster approximation. To solve the effective cluster problem we employ an extended noncrossing approximation, which allows for a transition to the broken symmetry state. At sufficiently low temperatures we find stable d-wave solution...

متن کاملSpin density wave selection in the one-dimensional Hubbard model
The Hartree-Fock ground state phase diagram of the one-dimensional Hubbard model is calculated, constrained to uniform phases, which have no charge density modulation. The allowed solutions are saturated ferromagnetism (FM), a spiral spin density wave (SSDW) and a double spin density wave (DSDW). The DSDW phase comprises two canted interpenetrating antiferromagnetic sublattices. FM occurs for s...
متن کاملBond-order-wave phase and quantum phase transitions in the one-dimensional extended Hubbard model
We use a stochastic series-expansion quantum Monte Carlo method to study the phase diagram of the one-dimensional extended Hubbard model at half-filling for small to intermediate values of the on-site U and nearest-neighbor V repulsions. We confirm the existence of a novel, long-range-ordered bond-order-wave ~BOW! phase recently predicted by Nakamura @J. Phys. Soc. Jpn. 68, 3123 ~1999!# in a sm...
متن کاملCellular-dynamical mean-field theory of the competition between antiferromagnetism and d-wave superconductivity in the two- dimensional Hubbard model
Cellular dynamical mean field theory is used to study the competition of antiferromagnetism and d-wave superconductivity at zerotemperature in the two-dimensional Hubbard model. The outcome strongly depends on the value of the interaction. At strong coupling (UX8t) a first-order transition takes place as a function of doping between pure antiferromagnet and pure superconductor. At weakcoupling ...
